Continuously suspending account.

During June I connected a second decoder on extra view, but instead of linking it as extra view they billed me for two premiums. I phoned and problem was solved but since my account keeps getting disconnected and says it's arrears I phoned a them a few times but still nothing during August a agent said she will phone me back and I'm still waiting. I pay my account every month how can it be in arrears. Airtime to phone them to fix the problem then you have to hang on for 15 minutes or more and every time they disconnect TV for their mishap they can't sort out I have to pay reconnection fees for something they didn't sort out from the start. The agents I spoke to wasn't very helpful and had bad attitudes. This is going on for 4 months now and still not resolved.
