Cost prices are competitive and hanging was seemless.

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

We were former customers of Constellation and had no issues signing up. We went back to Eversource for a while, but since Constellation's rates were lower, we attempted to sign up again. The process this time was HORRIBLE. I would speak to a rep who said everything was all set, then I would get a call that there were issues and have to go through the process again. This happened four times, and no one had a record of the previous conversations. We are very turned off by the lack of organization and communication with Constellation. We hope moving forward, we don't have any issues. My kids and in-laws used to be customers too, but we told them not to switch. Not worth the hassle.

When I called Constellation customer service to inquire if I would be able to get their new, lower rate since I had just signed up for their service less than a month before, the gentleman was very pleasant and helpful. They did give me the lowest rate and I was both pleased and grateful. 🐦💗
