They give you the Runaround when they must refund you

I accidentally made a payment to dstv on 30Nov. The very next day I called and asked for a refund. I was asked to send proof of payment, bank statement and ID. I did that on the same call which lasted 22mins. A few days later I got an email saying the query was closed and the money allocated to my account. A week later, no money in bank account. I call them and they tell me that the refund was never processed as a refund just credit to my dstv account ***6. At that point is was 15days since I first asked for a refund. They then keep me holding for 25mins claiming that my docs are missing, and then I was told they cant upload them on their system... all the while im paying for the phone call and they refused to call me back! I end up calling back on the next day and get confirmation that the refund should come thru within 7days. It has now been a month since I first asked for a refund but I haven't received it yet. I paid my premium end Dec when it was due but they haven't given me back MY money!
