"Constellation was good until I needed help and asked a question. They totally fell down at that point."

"Very good. The representative was very knowledgeable and professional."

"Very pleasant and helpful customer service. Was very eager to help and did and explained everything perfectly."

"My interaction was perfect. This survey is TOO long."

"Will not be renewing when contract expires"

"Sophia was great. I had to transfer service from a address to another. She resolved my problem through the chat. She sent me all the info needed and it was no long wait. She sent me secure link for my personal info, everything has been very professional and well taken care. Thank you!"

"Very good customer service."

"Well I wasn't supposed to have any early cancellation fees since I cancelled before the 90 day period, but I was sent an email for each account stating that I had to pay the fees. Do I ended up having to call yet again to get them removed, so hopefully that's the end of all this mess."

"Horrible! You illegally disconnected my electric and failed to rectify the situation when I called the first time. The agent failed to perform her duties and actually look into my account thus causing me incredible stress, inability to cook, be freezing cold and have my dogs do cold they were shaking."

"Your company is the greatest."

"Rates too high. Not competitive."

"I realize it's pretty much standard practice by all suppliers, but once the agreed time frame has expired instead of just going month to month fluctuating rate like eversource would do, constellation and others create a new contract with new terms previously not agreed upon when shopping around like cancelation fees. They then send this in a letter and it's up to the customer to opt out instead of being given the chance to opt back in. Let the rate fluctuate month to month like eversource would do as a supplier until the customer decides to call and opt back in to a new agreement. Send reminders or flyers inviting into a new agreement if you want but waiting on customers to opt out, while legal, just comes off as dishonest especially when adding a previously not added cancelation fee. I am aware it's customer responsibility to monitor but with all that goes on in people's lives it's easy to miss or disregard or just not receive the new contract in the mail."

"All in all it was a pretty painless experience."

"From start to finish everyone I had contact with was super."

"The costumer service representative, named GAILE, was extremely helpful in resolving my issue. She stay on top from the beginning until it was resolved. She was extremely helpful and understanding. I want sincerely thank her for looking into my concern."
