Recent Good Review from Connecticut Customer

Best Rate Available At The Time

Constellation had the lowest rate at the start of 2022 when Eversource's standard rate increased. There were no enrollment or cancellation fees. It was the best deal at the time that my previous alternate electricity supplier's contract was ending. Although this Constellation plan lasts for a longer term than I wanted, I can exit the plan at any time without penalty should a different supplier offer a lower rate.

Priceing

I have what i thought was a good relationship with this company everyone ive ever dealt with was upfront honest and true to their word. My issue is i thought i did well when i signed up for a 3 year fixed rate price per kilowatt hour @ 9.99 now im reading and see it is 7.69ish? i no i have a contract but one would think to keep a customer and remain honest they could have at least contacted me to see if i am interested to extend my contract at this price for and extended 3 years. I realize i have a contract and it is what it is but my thinking if you wish to keep a customer and keep an honesty repot going any company would give it a thought to put their customers 1st. Also i wish to let anyone and everyone who sees this i only wrote this publicly as i couldnt find any other waty to contact on this page... its possible their is another way in front of my face so sorry if their is i mean no dissing to this company as i said they have all been very good dealing with me and i never found any big issues against them. Lastly they were a company who introduced themselves to me and left me alone to make a choice without calling or emailing me to the point that id want nothing to do wth them they left me to make a choice without feeling forced.

Contracting with Constellation

I thought establishing the up front contracting was a bit redundant and could be more streamlined. This is why I gave account management only three stars.

Incomplete

I signed up but they didn't follow through. I gave them all of the info they needed when they called, but for some reason, it didn't go through. Can't recommend what isn't working.

Bad customer service-took three times to get the deal

Bad customer service, slow service. I had to correct the issue. Your customer service called me two times and did not correct the issue. It is like you did not want me to have savings before the summer and so because of your delay my bill was high. Delayed 3 months because your bad customer service. lady that called was rude and should not be in customer service, she did not correct the transfer issue. I corrected. I also missed out on a gift.

Horrible!

It took 5 calls because they repeatedly were telling me I wasn't signed up after emailing me confirmation numbers. Kept trying to change the price everytime I had to call again. End of story I am NOT a customer of constellation and would NEVER recommend anyone waste time with the run around I was put through!!!

Unfair

IN THE MIDDLE of my signing up for their 8.89c rate today they changed their rate to 9.49c. Honestly - it was 8.89 and less than 2 minutes later it was 9.49! When I called to see what was going on, they refused to give me the lower rate I had been signing up for. Wouldn't budge. And neither would I. Bye-bye.
