DSTV, quick to take money but refuses to reverse incorrect billing

I cancelled my DSTV subscription end of January, but the debit order still went off. I made inquiries mid Jan to find out the process, and followed the instructions. Since then I've been calling every week to reverse the debit order pmt, and every week I'm told i need to wait 7 days, as the previous consultant captured it incorrectly. Its a month later and still no refund for February service that I never received. 1 consultant says there is no number for the finance department, another today say there is no finance department at all. And will not let me speak to anyone else that can assist, they just keep wasting my time and airtime on hold waiting for something they have no idea what they doing.

I refuse to wait another 7 days, for a refund that should have been processed at least 2 weeks ago, due to incompetency. And I refused to make a debit order reversal to affect my credit rating, when I was willing to wait for DSTV to reverse the pmt, that should have taken at least 2 weeks, not a month and still not resolved.
