Inability to credit money due

I decided to down grade my package from premium to basic. Called in to do it a month before so that DSTV had 30 days to cancel. The call center person said no sir you can cancel the day before and we wont debit your account for that next month... I said are you sure..she said yes... no problem. So I called at the end of March to activate my down grade, call center person says ok but its too late your account will be debited for April!!! Now Im ****ed off.... They said so sorry nothing we can do but debit your account and leave it in credit. I said no I want my money back NOW! Sorry sir cant do it. So I asked for a senior person, got put on hold, cut off, called again, told my long story, put on hold, cut off again!!!!. Finally after much frustration and 45 minutes the best they could do was pay me back in 10 days. Mid April came and went still no payment. I called again same stupid call center run around until Mr Mpho Leimela understood my problem and promised it will be paid back in 5 working days. That would have been 29/30 April, last week. 2 months have gone by and Im still not any closer to getting my money back. My ref# 195 174 368. To make matters worse they cut me off early
