Appaling SERVICE from DSTV

Its a pity I have to turn to Hello Peter to get a response for my query. On 2 April M-choice debited R5159 from my bank account after I had clearly told them to cancel the year payment plan last year around the same time after they deducted a similar amount. I was surprised to see this deduction. On 8 April I called their call centre, spoke to Zikhona. I informed of the error. I also reminded her that last year I requested for a month to month payment option and would like to downgrade my package. She told me she had initiated a refund for the amount debited from my account R5159 - R139 for the new package I requested and will be refunded with R5020. She advised that i will receive my refund in 7 days and that a supervisor willl call before end of day to confirm the refund. I phoned back the following day to check if the query was cleary captured. I spoke to Lumka and she advised my refund will be +-R4600. She said the supervisor will call to explain the reduced amount. I did not receive a phone call. I phoned back and spoke to Andile and Siphokazi who informed me the supervisor will call me back. Its almost 10 days now, I have not received my refund, the supervisor has not called me back and my refund amount has not been rectified. I phoned again today (17\04)and I was told to hold for the supervisor. I stayed on the call for over 30mins only for my call to be cut off and no effort made to contact me back. This is appaling service. I do not have R5K lying around and have been inconvenienced immensely by your careless errors. I am giving you until end of today to refund all of my money. R5159 or you can cut off your connection.
