"Overall, I had a positive experience. I tried to resolve the issue online but never received a response to my email other than the initial auto reply. As I mentioned above, the auto reply said that I would receive a response within 2 to 3 business days. A week went by with no response which caused me to call the 800 number"

"The rep was very patient and helpful. She couldn't have been nicer."

"Customer Service Rep was knowlegeable, efficient and courteous."

"nicest experience from a company in years. no hassle and answered all my questions with a positive attitude. great service!"

"Good experience - I initially contacted my utility provider, Delmarva Power, after receiving a voice mail message on my landline twice stating that This is an apology call from your utility provider re: an over charge by my third party supplier & press 1 to receive my rebate check & 30% discount. I did not press 1 as the caller did not identify himself as Delmarva Power (just 'utility provider') & did not identify my 'third party supplier' as Constellation - so seemed suspicious & I wasn't sure what would happen if I pressed 1. I am becoming more & more concerned re: scams calls that seem like they come every day even though I'm on the 'Donotcall.gov registry' & report them. The Delmarva rep that I called said they would not call, but would send a letter. The Constellation rep said she saw no evidence of an overcharge or rebate due. I asked if there had been other callers re: this message & she said a few that did press 1 & then a click & nothing - So my question/concern is who are these callers & what are they looking for when the person presses 1 ?????"

"Great service.Your representative was competent, cordial, and kind."

"Very good..wonderful employees"

"Constellation did not follow my instructions/request for starting my service and it resulted in an extra billing cycle during my contract. It was clear that it was done intentionally to increase revenue and resulted in double billing for hundreds of kWh."

"My experience was very good, agent was great trying to find answers for me."

"Excelente la jente en general muy amable y enpatica.."

"My general experience was satisfactory in that I was transferred immediately to a representative that could help instead of being shut down before a representative with specialized function could be reached."

"This experience was undoubtedly the best experience I have ever had in a decade or more. I had been having a less than desirable day before I called, but having such a pleasant experience with your agent changed my outlook for the entire rest of my day."

"Agent was knowledgeable, friendly."

"Very knowledgeable staff. Kind personality. Answered all my questions."

"On Wed the 11th it was horrible because the represenative made a big mistake and took too much money out of my account and it caused me a hardship with paying my other bills, and it has not not been put back into my account. as of today I need my money now i am a senior citizen on a fixed income. i checked in with my bank, and they said you all need to get in touch with them so that they can put the money back in my account"
