Wow, they really need to come up to the 21st century

(2.4 / 5)

  Price for Gas is great, the problem with this company is their technology is pathetic, it is a challenge every time I go on line to pay my bill or something,, they are using a payment service so it costs extra to pay on line but I can deal with that,, the main problem is the website is very slow and messes up all the time,, then I hit live chat and it doesn't work either,, I am probably changing companies just because of the headaches involved..

Sloppy Billing and Delay Payment Credits

(2.3 / 5)

  StarTex gives you 15 days to pay your bill and then delays crediting your payment for about 6 days in my experience. If you miss your 7 days to get the bill and get payment mailed to them, you get socked with a late charge. For the first time in 40 years, we were "late" on a payment even though we paid them within 2 weeks of receiving the bill. Beware this company.

Be Careful!

(2.3 / 5)

  Startex is a company that will be sufficient when everything is running fine. However, I had a payment sent a few days late (no late payments for previous 10 months), and they cancelled my power WITHOUT any notification. The power was shut off when my wife was home with our newborn baby. They threatened to keep the power off until I transferred payment to them, but then customer service completely fell apart when I broke off my contract. They keep calling for their final payment despite breaking the contractual obligations of warning us about service termination. Since that time they have added $300 more in fees. Be careful, this company is nice when you are paying on time, but miss one payment, and they will bring the house down on you!

Big issues - Faithful Customer + Contract of Promises

(2.3 / 5)

  Been with StarTex for 2 years and have been very satisfied. Billing is clear and I especially like that if I've forgotten to pay my bill by a certain date, StarTex will send me an email reminder a few days before the bill is due. And had alway recommended @ more than 50 times in pass years.However, until I saw that the new rates they're offering for existing customer @ June 17, 2012, so I had sign up early.After all, I never had any problems with their service. Always helpful over the phone and online, they made it easy on me every time I've had to renew early. But, After little over month later got an unexpected renewal contract mail, said that due to StarTex Power were purchased by another company and things have to change.What ???!!!! Why me???So, now the StarTex Power staff saying they cant find my contract and they want me to use their month-to-month plan rate 20 cent per KWH.*(use under 500 kWh )That rate is too high !!!!!! Very dissapointing !!!! jacked my rates sky high!!!!What happening about my last early renewal contract that was promises to me ??? That was @ June 17, 2012 and June 18, 2012. I did sign up online and got confirmed two time by email, again !!!!On June 18, 2012 they had told me their computer system had little error, but they will honor my online renewal contract.That why she had resend me another WEB ### CONFIRMED AND LOCK ME IN FOR another three months renewalcontract new rate @ 9.1 per kWh.Do they want my business ??? Decision, decision, decision ???!!!!

You have got to be kidding!

(2.3 / 5)

  Good grief! I just got my first bill from StarTex and I believe that I chose the wrong company to provide my electricity.I retired and moved from MN back home to TX last month and I can't believe how much more expensive electricity is here than with my electric coop back in MN. I am now paying 12.333/KwH here after paying 5.4/KwH in MN. I live in a 750 sq ft apt and I make a concerted effort to conserve on my energy usage. The very same amount of KwH would have cost me $35.91 in MN rather than the outlandish price of $81.99. $46 Is $46.regardless of whether or not I am on a fixed budget or not. It's illogical to keep paying a high rate like this one! After only one month with StarTex, I'll be looking elsewhere!

Poor Comunications / Customer Care

(2.2 / 5)

  On June 13, 2024 I switched to Constellation via telephone conversation with Constellation sales person. At that time, the person reviewed my credit after I unfroze it for a day. He stated my credit was excellant (827). He said paerwork would be in the mail to me to complete and sign. The paperwork never arrived afte 11 days from call. Today, 6/24/24, I received a letter from Constellation stating my enrollment has been canceled!!! This letter was dated June 14, 2024 and was mailed June 18th!!!! They stated the reason was that they could not access my credit score (AES) from Equifax. In my opinion, this nothing but BS (why no call to me to straighten out problem? My credit score is excellant and Constellation sales repr confirmed that with me over the phone on June 13th. Their letter was signed "Constellation Customer Care" - I don't believe I received any "Cusotmer care" in thier letter.
Fortunitely, I found a more reliable gas provider. In the meantime, Constellation has lost a customer for life!!! due to this lack of care for a potential new customer.

Hate Constellation Energy

(2.2 / 5)

  Was not given all the facts about my rate . So many pissed off customers that you can NEVER get anyone to answer in customer service. The only way to talk to anyone is to talk to sales . Go figure.

Worst Customer Service Rep

(2.2 / 5)

  I was moved to Constellation Energy some years ago, I initially signed up with NewTex Power and I guess Constellation bought them out. I have always been happy with this provider, even as a month-to-month customer, and even when we had the winter freeze here in Texas earlier this year. I was on a contract when I initially signed up, but once my contract ended I went month-to-month. For YEARS I have had no problems. The last 2 months I received a bill for over $600 and this month almost $800!! I called 2 days ago to get a fixed rate and the system was down. The agent and I discussed the rates and plans and I was ready to make it happen, BUT Constellation's service was down, so the agent said he would call back, he also gave me his info & ext. to call back if I didn't hear from him. Today I made the call again, but got Luis...he told me the previous rep was busy but he could help me. By the end of the conversation, he was literally mocking me, not letting me get a word in, and talking to me like I was a child. I asked to speak to the rep I was originally working with and he told me he would pass the word along, only before letting me know "he's going to tell you the same thing I just did, and that's why you should accept what is given to you at the moment it is offered!" and hung up on me! After 14 years of being with this energy company, it took one unprofessional act for me to walk away. It is not even worth my time to try to call and speak to someone else. I just changed energy companies. As an Army Veteran who has heard, put up with, and been through A LOT, I can honestly say Luis is the worst customer service rep I've ever spoke to in my life. Sadly, because of this instance I will never go back to Constellation.

Horrible customer service, stay away

(2.2 / 5)

  I received a letter of automatic renewal but didn't want to renew with a much higher price, so I called the customer care number on the letter to cancel the renewal. The company didn't give the representatives who answered this phone number authorizations to do cancellation, so I was transferred to representative that can do cancellation. However I waited for over 30 minutes and still nobody picked the phone. I tried again later in the day and the same situation happened. It looks like Constellation deliberately made the cancellation process difficult for customers. The company does sound dishonest and does not have integrity.

Customer Service needs training

(2.2 / 5)

  The price is good. They only sent me bills every second month then include a late charge of $10 for the previous month. They did this for the entire year. I called it in in customer service but rep insulted my intelligence by saying its the mailing system caused by covid. I got all my other bills each month they were due....For the year they charged me $60 in late charge for bills that werent sent. They also told me its my responsibility to call in to query my balance each month.

Wow real jerks

(2.2 / 5)

  We had constellation for two years. Paid on time, never had to actually talk to anyone and Oncor did all the work if there was a power outage. So we switched providers for a better deal. My wife accidentally forgot to pay the bill the 2nd to last month. I got no phone calls, no emails, zero notification until a pink slip showed up saying we had 10 days to pay or they're cutting off service - WOW. So I immediately paid the past due amount only to have a notification from their collections department show up two days later. Dude - I have a perfect payment history, its a flipping pandemic, you made zero attempt to contact me - this was such a sleazy move. I am so, so, so thankful we made the choice to leave. So they'll be great, just don't make any mistakes or you'll be dealing with their nonsense. Seriously - one missed payment with a perfect two year history. If I were constellation I would have called just to check on me to be sure everything was okay since it is so out of character. I cannot stress enough that I would not recommend constellation to anyone.

Get the billing straight

(2.2 / 5)

  For whatever reason, they couldn't seem to get their billing aligned with AGL and so sometimes my bill one month would be low (term cost) and the next it would be close to double cos they're trying to recover their money. I can't budget for that. Is this a problem now for all gas providers or is Constellation just especial crappy?

Terrible online experience

(2.2 / 5)

  when I did finally sign on I had to enter my account number which I did not have in front of me but you would wonder once you sign on to your account all that information should be there why on Earth would I need my account number if I have everything else I mean ask for my social security number my birthday why does it have to be an account number no one can remember that and I wish there was a way it was less people oriented and more online oriented why can't I change my billing to electronic billing my payment billing doesn't seem like a very well design website but I've only started which should have been the easiest part we'll see you later or maybe it's time to move on two or more 2020 friendly world

The Pro's and Con's

(2.2 / 5)

  While I was blessed to gain service through them I felt that I was being over charged. I was unable to use my heating nor hot water due to my water heater was needing to be replaced but my bill never reflected a lower amount which it should if I wasn't utilizing the service at the time and this continued for months.

  When I set up the service, the operator did not put in the correct address for the billing statement. I went 2 months before I got a bill! Very frustratingWhen I called to get the address corrected, it was a 20+ minute phone call & I had a huge bill to pay. Need to work on customer service!

HORRIBLE billing and account management

(2.2 / 5)

  On 7/30/18 we began service with Constellation. After many calls in Aug & Sept asking for our bills, we finally received our 1st bill. I paid it through my bank on BillPay. A week later I received a new bill, it showed my previous balance as unpaid, so I called and the rep said my ACH/Electronic BillPay payment was NOT received. So I contacted my bank obtained all of the proof the rep said I needed and I submitted all of it to Constellation. 3 day later I was notified by email that the proof they requested and received was not sufficient and they would NOT be able to credit my account. I called and the rep said they don't deal with those type of calls and the best he can advise is for me to email customer service. I emailed once every day for 4 days. Finally I received a response. It was the exact same response as the initial one (submit all forms again). Back to square one I resubmitted everything they asked for and their response was a 2nd notice of disconnect. It's been a horrible experience and now I have to deal with my bank, dispute the charge and pay the bill again to avoid disconnection. Meanwhile a 3rd bill has showed up! their billing seems to be very delayed I received 3 months of bills in 3 weeks. Will most likely pay to get out of the 1 year contract and go elsewhere. Horrible customer service to say the least. I have NEVER experienced anything like it.
