DSTV has done it again

3 months ago DSTV changed the date of my debit order without my knowledge and double debited my account. I was told I had to go to the bank to reverse their error and then pay that months fees which I did. I was also told by two different people that they had changed the debit date back to the 25th. So imagine my surprise when halfway through May my DSTV was disconnected due to non - payment. When I phoned to query I was told there was no debit order on my account and I needed to pay cash plus reconnection fee which I refused to do. The lady in the call centre was going to get her supervisor to phone me. I'm still waiting. Then the 25th of May arrives and they double debit my account again, being a single mother I cannot afford this so I go back to the bank and reverse it. 5 days later on Friday afternoon they disconnected my DSTV just before the 4 day weekend. I phoned them to discuss the situation and after 53 minutes on the phone - most of which I was on hold - she says she'll get her supervisor to phone me back. It's Monday now and I'm still waiting. Very annoyed and unhappy.
