Terrible company and terrible service. Entrust Energy sold our account to another company without any notification to us!!! Until yesterday we received another company's email that we own them money and we need to pay past due fees (we thought it was a scam because we never signed anything with it), and I called Entrust, then I was told that Entrust Energy sold us to that company 2 months ago!!! They said they notified us, but we chose paperless method and we never received any letters, and I checked all email records, NOTHING!!!
