Unfair billing by dstv

I love dstv but lately it seems they just want to rip people off. At first i had a debit order set for my payments, one month the debit order bounced and within almost a moth later, i checked and the connection was disabled by dstv. I was still away so i decided to reconnect when i get back. However when i tried to reconnect after 3months i was told i owe dstv 2500 which had to be paid before i could reconnect. This didnt make sense as my connection was disabled the whole time. I called their customer service which cost an arm and leg of airtime and all their assistant said was that she also doesnt know and cannot reconnect me until i paid the amount. So i just paid the amount and cancelled the debit order so i pay as i watch. But now i hav the same problem, i paid my account and was connected the whole of january 2015. My next payment was due on 6 feb 2015 for the month of feb, however by the 5th my connection was disabled and according to their site i must pay R1228.00 before reconnection. This dont make sense as the premium payment is R665.00 where are all these fees coming from? I wont call them again as it costs a lot of airtime and the consultants usually have no idea
