Bad service Dstv

I am on a pricelock package and was recently over debited by lots of money. I contacted Dstv and have now been struggling for weeks to get my refund from them although they say it has been approved. They were quick to ***** my money but very very slow in correcting this issue. Bad service from call centre, whatsapp and sick and tiered of having to try and speak to a machine or *********** call center staff.
