I had an account with XXXX XXXX. When I moved, I took the rented equipment with me. The supervisor advised me to use it with my new account. The representative removed any new equipment off my order since I already had it. I received a bill saying I owed XXXX for unreturned modem. I called and explained. They said they would fix it. I kept receiving bills and kept calling. I finally just cancelled the service and returned the modem. I explained why I was cancelling. They sent me a postage paid box and I used it to return the modem. They are still charging me but I gave up calling months ago.
