Totally annoyed and disgusted

There is a problem with my dstv account (DSTV Side)and they keep disconnecting my dstv, when I phone to have it reconnected they have no idea why it has been disconnected and they reconnect it, this has happened for 3 weeks in a row now at least twice a week, my dstv was switched off on Thursday last week and they will not reconnect it telling me I now owe R579.00, which has apparently been outstanding since July so if this amount is outstanding since Jlu why has my DSTV been working???? I asked her to send me a statement which she did and it does not make sense. I phoned again this morning a lady by the name of Betty helped (very helpful lady) she then told me the error was on there side something to do with dates on the system and she said it was a DSTV glitch, she told me she would speak to her supervisor and get it credited, she put me on hold and the call got cut, I phoned back and got told I cant speak to her but she would call me back, I have received no call back and my dstv has still not been reconnected... if the problem is their side why should I not have DSTV a service I am paying for?? I have tried phoning numerous times and my call keeps on getting cut, not impressed
