Left in the dark

(1.2 / 5)

  I was moving into a new home, scheduled my power to start, and a week into my new home, power off. Friday, 4:58PM. I call immediately, they tell me they have no record of my account or name, and there is nothing they can do until tomorrow, I'm given fake numbers to call back, fake operator names, and no power for 4 days. The kicker is, the only reason my power came on, is because I gave up on Startex and switched to stream, who had my power on in less than 5 minutes after account creation.

Very very poor customer service

(1 / 5)

  I recently had the unfortunate experience of dealing with Constellation, a gas company that falls far short of expectations in almost every category. From their unreliable service to poor customer support, there are several reasons why I would advise others to consider alternative gas providers.

First and foremost, the service provided by Constellation is notably inconsistent. Frequent outages and delays have been a common occurrence, leading to significant inconvenience. This inconsistency not only affects daily life but also raises concerns about the dependability of their supply, particularly in critical situations.

Moreover, the customer's experience is further undermined by unhelpful support staff. My attempts to resolve billing issues and service disruptions were met with long wait times and generic responses that did little to address the underlying problems. This lack of effective communication and support is frustrating and unacceptable from a service provider.

On top of the unreliable service and poor customer support, Constellation's pricing is often higher compared to other providers. Considering the quality of service they offer, the cost does not justify the experience. There are numerous other companies that provide more reliable service at competitive rates.

In conclusion, based on my experiences, I would strongly recommend exploring other options before considering Constellation as your gas provider. It's crucial to choose a company that values customer satisfaction and reliability, neither of which are evident with Constellation. Make sure to research and opt for a provider that better meets your needs.

Unethical Company with Misleading Warranty Coverage Promises

(1 / 5)

  VERY UNETHICAL PRACTICES - Called to inquire about electric service as their home warranty perk with being a customer seemed like a good deal which would protect us from the possible high costs of AC and water heater repairs. Even though their price per KW is higher, my wife and I concluded it was worth the piece of mind of future unexpected repair expenses. When signing up, we asked a lot of questions regarding coverage and were told everything is covered unless specifically excluded which seemed like very few things which were mainly maintenance related. Fast forward, and our A/C breaks down 6 months into our contract. We were happy to know we wouldn't have to worry about this, especially with twin babies at home during the Texas summer months. We filed our claim and they sent one of their 3rd party companies to inspect our A/C which left us with an invoice of 3500 and said to call Constellation regarding repair coverage. Upon calling, Constellation's warranty department which goes by Home Protect, proceeds to tell us our part needed is not covered and falls under items excluded in the contract. When I ask to please forward contract reflecting this, they tell us they cannot because it was in the welcome package we would have received through regular mail. I eventually reach a service rep who is able to forward us the original welcome package that was sent to us with contract included. Upon review, we notice it Does Not mention our part as one of those excluded from coverage. We call Constellation's warranty claims department back and get transferred to same manager who we let know that we were able to get the contract and can now see it does not show our part as one of the excluded ones on the list. She then changes her approach to tell us in a very condescending manner that actually if it's not on the list of covered parts, then it's assumed it will not be covered.

Bad experience , BEWARE

(1 / 5)

  Beware of shady practices. I was told no early termination fees when the guy came knocking at my door. All he was pushing was a lower rate, he was also very pushy. I would not recommend using this company

Scam

(1 / 5)

  Couldnt set me up online and needed me to call a representative to give information. Then proceed to try to sell many insurance products to me. I said it was a scam to make me call in and talk to him and he was annoyed because he IS a sales representative! It was all a big hassle and I didnt feel comfortable with them. Also received many solicitations after signing up.

Zero Reliability

(1 / 5)

  This is a horrid company and their is no level of customer service. It is based on sales and that is their bottom line. It is structure to syphon from its users and to get people into a rock and a hard place. DO NOT go with this service provider!

Do NOT do it! They are HORRIBLE!

(1 / 5)

  They will drop you as a customer, after signing a contract, without even telling you. THANKFULLY, I needed a copy of a bill for a new resident form so I was locating my account information to set up an online account and I just happened to find out Im not longer a customer. I should have gotten an email is inaccurate, and had I not called, I wouldve have been late on my new company (who they shared my info with unknowingly) first bill which was due the next day. Over all, dont go with them. Sure the rates look better, but customer service is absolutely horrible and they dont care about respecting their customers. 0 reason to discontinue our new contract one month into owning our new home.

Ive been with them for almost six years

(1 / 5)

  I have been with this company for almost six years and I regret it all the time. Of course Im locked into a contract so I cant change right now. They have turned off my gas due to a mistake on their part but instead of apologizing and getting my gas back on today, they will get it on tomorrow. I explained that I have a medical condition and that it is supposed to get down to 34 degrees tonight but nope, tomorrow. We are moving soon and I will NEVER use this company again!

WORST GAS COMPANY, PERIOD!

Worst company to deal with

(1 / 5)

  I found out today that I am locked into a 5 year contract with this company!! Would NEVER have signed with this company had I been told that up front. Was charged $2,000 for an early cancellation fee! Extortion! Just my opinion , but buyer beware!!!

Horrible horrible and slow service

(1 / 5)

  They disconnect service without courtesy calling or emailing. Dont have same day service and very limited customer service hours. Their representatives dont even know the customer service hours. When you need you reach a specific department they transfer you and then it goes to voicemail. Its a joke.

Dont ever go with Constellation.

Predatory Pratices

(1 / 5)

  Intentionally not providing adequate contact to customers about account issues which lead to late fees, account closure, and issues with equipment at my home being replaced. Wouldn't reimburse us for damages.
Predatory company, should be closed and CEO should be in prison.

Use of fear tactics

(1 / 5)

  About 10 years ago we had 2 heat pump systems replaced by then BGE. They did a great job. We took out a service contract that we cancelled in 2019 that we cancelled in 2020. We recently scheduled a service appointment with now Constellation Homes. I took off work on this day but they never showed. I called to inquire I was told that they will NOT be coming out as I was in 'collections'. Every time I tried to contact their billing department, I was "disconnected" or could not get anyone to respond. It took a complaint to the BBB to get them to contact us. Turns out that there were NO collections and they were trying to recoup money from my cancelled contract. They now offered to come out but I declined. They are dishonest in their billing, lack any customer service and they cost me an entire day of lost wages. And my heat pumps still have not been serviced.

Rapping off customers with high bill

(1 / 5)

  Fraudulent fraudster company, billing customer of service they did not consume, how will I not be in the property, every appliance off switch, and Constellation still sends me a very higher bill than the months I am actively living in the property, and even after calling to close the account? Thrives, arm Roberson with out Guns

They loose payments

(1 / 5)

  They don't accept electronic payments, claim checks were not received as soon as you cancel the check and pay the bill they run the held check through to charge a NSF, its a game of greed don't play. Its obvious their bill payment process is incompetent.

Gassavings.com is the biggest scam in the market!!!

(1 / 5)

  Signed 1 year contract via gassavings.com with Constallation in April 2023, but they signed me with ganatural gas for May 2023, then cancelled, fined me -100 bucks, then switch to Constellation. Did not received even 1st bill from this natural gas provider, but looks like a nice provider.

They cancelled ME!

(1 / 5)

  I was happy to sign up with Constellation for electricity. A rep called to welcome me to Constellation about a month ago. Then this week I got a letter saying I was cancelled. No reason. So it was back to Apples to Apples to find another supplier.
