Account department is the worst ever

I'm on the premium price lock package paying by debit order. The last three months they take more than the agreement from my account. There reason is that I'm in areas. Firstly how can you become in a areas if you are on debit order(I don't use box office & not connected to the internet), secondly they refund me then with in seven days my service is suspended for areas again. I now can understand why people are leaving DSTV. That is my next option also. Netflix are looking much better and cheaper.
