The bad service continues

The bad service continues. I upgraded to the premium package and was debited R 1 697 in November.When I called the call centre I and requested that my money be returned as I was charged for an upgrade and my account was doubled debited without authorization , I was told by the agent that I am not the only customer who was double debited and that she needs to log a call to refund the money, the call was cut while I was holding for her to log the call. By the 3rd call I refused to explain my self again and insisted on speaking to a manger and was told by the call centre agent that the manger refused to take my call , after maintaining that I want to speak to a manager , I was eventually transferred to a teamleader who confirmed that I was debited in error and will be refunded within a week.I explained that it is unacceptable as I had other financial commitments and returned debit orders due to their mistake. On 01 December I was again overcharged, my account was debited with R 1208.00 instead of R 399. This incompetence and terrible service is really unacceptable. I now had to pay a total fee of R 480 for returned debit orders due to the unauthorized amount being debited by DSTV. I have been a customer for many years and always paid by debit order , never missed a payment and now have to be inconvenienced and fight for MY money. I request that the overcharged amount be refunded and my subscription be cancelled effective immediately .
