Service keeps Disconnecting

Good Day<br> <br> My Dstv Service has been disconnected 4 times in August due to a debit order that does not go off. I have sufficient funds in my account and yet the debit order does not go off July, August and now again. My bank shows no attempt from dstv either. I have transferred money to dstv via eft yet my service disconnects. Every time i call in, they connect my service and say they will investigate further. No one comes back to me. I have to explain the problem everytime i call in. The agent ask the supervisor for help. Yet no one comes back to why they do not debit my bank account and why they do not receive my payments. I give up. I don't know who to complain to anymore. This service has been pathethic.
