I received absolutely nothing from…

I received absolutely nothing from constellation once I signed up except about rewards program. No account number, no here’s how you sign into your account. When I went to the site it said I had to link an account??? Gave me three options one was using my account number??? Well would have been fine if I had it. I took a wild guess that the last option was asking for the meter number which I had from the notice from PUC that I switched prividers and it worked. I then saw I owed you money. Since I hadn’t gotten a bill at that point I never would have known without calling you. I did get a bill in the mail after I figured out how to link my account. (A miracle as our mail set is sketchy)I wasn’t even sure if I was support in paperless. I never had a company leave you guessing as to what your account number is, that your officially with them or any other details until i signed up with constellation.

Response from ConstellationMay 13, 2026

Hi Lynn, We're very sorry to hear about your experience. You should have received a confirmation email once you completed your enrollment and a welcome packet once your service started at your address. This packet would have your customer number and information about your rate and plan along with the appropriate paperwork such as your EFL. If you are able to log into your online account, you can elect to enroll in paperless billing, which means you should start to receive your monthly bills via email rather than by postal mail. We have sent you a message to the email address used to leave your review. If you could please respond with the requested information, we can escalate this to our customer care managers to look into and check your information against what you send us to make sure it is correct in our customer database. Again, our apologies for your experience. We appreciate your feedback.
