We were former customers of Constellation and had no issues signing up. We went back to Eversource for a while, but since Constellation's rates were lower, we attempted to sign up again. The process this time was HORRIBLE. I would speak to a rep who said everything was all set, then I would get a call that there were issues and have to go through the process again. This happened four times, and no one had a record of the previous conversations. We are very turned off by the lack of organization and communication with Constellation. We hope moving forward, we don't have any issues. My kids and in-laws used to be customers too, but we told them not to switch. Not worth the hassle.

Took too long to communicate and start service; decided to use other provider by the time you processed my request.
Response from ConstellationApr 9, 2026
Hi Deborah, We are sorry we could not meet your expectations when switching. Unfortunately, the switch process can take some time because the utility must approve the request. We appreciate your feedback and will share it with our Care team. If you change your mind, we welcome the opportunity to be your energy provider. Thank you.

I subscribed to a 3 month plan to try your company out. I was disappointed. First, you said my plan date would expire after 2 months instead of 3. I called customer service. The person I spoke to wasn't very intelligent. He couldn't figure out when the end of 3 months would be! Finally, we got that straightened out. Later, I had to call customer service again because the ending date of my contract went back to the 2 month date. Again, customer service had a hard time with math figuring out when 3 months would end. FINALLY, it was straightened out. Other than customer service, the actual electric service and billing were fine;
