Price is a little higher than I want, but the length of the service was what made me switch back to Constellation.

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.

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.

A very happy customer

A very happy customer! I’ve been with Constellation now for many years. I love that they keep me informed of how many kilowatts I have used on a weekly basis. It gives me an idea of how much energy I have used and informed on those days when they are higher. I keep tabs on my account. I appreciate knowing and anticipating what my bill will be each month. By the same manner, I welcome those tips on how to conserve energy and lower my bill.

Satisfied customer Maggie Young

This is the best electricity company ever. I'm on a fixed income and I try to keep my usage low. Thanks for letting me know about the working of the air conditioner. That really help, if something is not working, Id be able to have it fixed before I began to lose money I can't afford.
