I absolutely love being with Constellation! The customer service is always efficient. The communication is clear and the best part is after an interaction I feel valued as a customer. If you’re not with Constellation, I mean what are you waiting on?!😀

Constellation Was More Expensive
I received a letter saying that I was being signed up for Constellation energy aggregation without my knowledge. After reading the letter which seemed purposefully confusing with the way they presented their prices and wording, I could see that the Constellation price was higher than what I was currently paying for residential electricity. There was a code to go online and complete an Opt-Out form or an option to mail it in. After finding the correct web page I completed the Opt-Out form online. I do worry about people who may have difficulty reading or comprehending this due to age or illness being charged more for their energy needs because they can’t understand the paperwork or the Opt-Out process.

No information after signing up
Once i signed up, I never received a welcome package or account number. This happened for 4 different homes that I signed up for service. I had to use the online chat feature to get the account numbers. Also, had a terrible experience with their "identity verification" process.

Easy transition to Constellation
Transition to Constellation could not be easier or smoother
I’ve had no communication or updates…
I’ve had no communication or updates form your company after signing up. I continue to receive bills from my prior provider at a significantly higher price now that my contact has expired and I still don’t know if you actually set up my account or just lost my order.

Happy Camper...
For so many years, since I transferred my service to Constellation Energy, I like their energy rate. They have the cheapest rate compared to my previous providers. Their customer care service is very helpful and easy to talk to. They will try their best to solve my concerns or issues.
The customer service is very good
The customer service is very good. They have helped me many times.
Customer Service needs help
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;

I have been with constellation for 15…
I have been with constellation for 15 years. I stay with them because they don’t go up all the time like electric companies do. They’re pretty fair on pricing per kilowatt and when you call to talk to someone at constellation, they have not been rude. They have been kind and help with your problem if you have one or question.
My review
I have been with Constellation for sometime now. Customer Service is really good and their rates are very competitive.
