Bad customer service Multichoice DSTV

I mistakenly paid R4000 for my child school fees in my husband's dstv account immediately called the call center. I was advised the money is reflecting and the account is in credit however they need my banking details which i would have to go take it to the walk in centres. We have gone to 3 walk in centers they requested for my 3 months bank statement and we went back to hand it in, now we are told to go to Randburg . This is a nightmare I pay this account every month and now that i need the funds back to pay for school fees and to be assisted DSTV is giving me bad service.I want my money bsck and cancel the subscription.
