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.

I absolutely love being with…

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?!😀

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.

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.

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.
