I have been double billed by this service for 7 months. I cancelled the service in October and I am still being billed. I have faxed the proof of double billing 3 times and I have been on the phone countless times. I am actually on hold for 30 minutes as I am typing trying to get a supervisor on the phone. I called earlier and was told that the rep would not put me through to a supervisor and she hung up on me. I have never been treated so poorly. I have absolute proof of the double billing and they will not credit me. I don't know what else to do?
