The absolute worst customer service

! Hi I would like to file a complaint about Rain. Rain and their consultants have left me extremely disappointed. I got a message that I was being handed over for debt collection. I stopped using their WiFi over a year ago. I have requested that my 5G service be cancelled. I have sent letters requesting cancellations, and there has been no response, including requests for a call back. Now I am getting this type of SMS: DO NOT IGNORE!
