*****ulent DSTV billing

I have recently been double billed for my monthly DSTV subscription. After speaking to a customer care consultant on the first occasion, I was told that I was billed for a holiday home decoder in addition to my normal subscription. I do not have a holiday home and told the person this. She then promised to cancel the holiday home subscription and refund my money. I have now contacted Multichoice 6 times and end up with the same feedback each time - they tell me that I activated a holiday home decoder in a previous call but will cancel it and process a refund. In addition, the problem has been elevated to a team leader. This is extremely exasperating and it's like talking to a wall because every customer care person keeps reciting the same feedback. I am beginning to believe that a *****ulent transaction has been processed and hence the reason for me making no progress with this matter. It is either this, or customer care people (and their team leaders) are grossly ***********.
