"Constellation had been my energy supplier for over 8 years until a friend lured me into a useless company. And when I was switching back just after one year I understood myself. And during the process of switching back, the lady who took me through was wow! She had all the qualities of a good customer service skills and I give her 5-star rating. It means a lot for a person to switch from a company and come back. I love you Constellation and I hope you will continue to deliver to me like I was with you earlier before I made that mistake of switching. More grease to your elbows."

"I had been a customer of EMC for about 20 yrs. I was out of town & missed a payment by 2 days.Bingo, I was charged their standard late fee of 10%. Not long after that I received an invitation from Constellation & accepted it & have been with you for over a year & just renewed my contract for a year. Keep up the great work with customer service even though your rates are not the lowest in town. The few times I have called, I am answered promptly. I should thank EMC for charging me a late fee after no other instances of late payment in 20 years. Otherwise, I may not have changed gas providers."

"Because of the high rates I would rate it unsatisfactory"

"been a customer for over 10 years. only called CS 3 times. last 2 were confusing calls and had to ask to speak to supervisor."

"I’ve been a long time customer and only switched because the service was not available in my new area"

"excellent knowledge and sevice. quick and efficient"

"Since using Constellation as my energy supplier, I have been very impressed with the service."

"After being transferred to the correct department my issue was handled well. The agent was quite thorough and competent. I was impressed!"

"Pleasant ad understanding of my issue"

"My experience cure is not great. This is the second time in 3 years my payment has been either not applied or misapplied to my account."

"Because of the high rates, unsatifact"

"I don't like the high termination fee from my contract. It should decline over the life of the contract. The rest of my Constellation experience has been good."

"Great after I obtained a valid phone number"

"For some reason my standard EFT payment thru my bank was rejected by you and returned, even though I or my bank had made no changes in the set up and you had been accepting that exact payment set up (customer number, etc.) for the past 8 months. The one question that you were not able to answer is why suddenly did you reject a payment that you had been accepting? The agent did not have the payment rejection and information available to investigate the why question. I was able to pay by credit card online and avoid a late fee. I also went into my banking account and reintered the customer number to be sure it was accurate. Hope this fixed it."

"Your phone agents seem to need training on renewal energy guidelines provided by Constellation. I still am not sure what happens to my excess energy my solar panels produce so I will need to cancel my service to be certain I get reimbursed for my excess energy as no one can give me anything in writing"
