ShowMax + Dstv Premium Package nightmare

I’m on Dstv premium and have added ShowMax to my profile. This is supposed to be included free of charge for premium package subscribers. In the past year Multichoice has deducted R99 for ShowMax subscription. You would have thought they’d fix this the first time it occurred but this error keeps popping up. I managed to get refunded for the 2 times it happened however my attempt to get refund for last debit order which occurred this year in April has fallen on deaf ears. I reported the matter shortly after debit order of R99 went off on the 2nd of April and nothing was done about it. I then reported the matter again on the 14th of April and I was assured I’d be refunded in a few days but the gentleman couldn’t say exactly when. We are now in May and I still haven’t been refunded so I decided to reverse the debit order from my account. I then get an sms from Dstv to pay the R99 which I had reversed. I then contacted Dstv on live chat but Kgabo Maano was unable to assist me. Why does this keep happening? As soon as my contract expires I am cutting my ties with Dstv.
