DSTV MULTICHOICE POOR CUSTOMER SERVICE

In August of 2015, I called into multichoice to cancel my subscription as i no longer needed the service. To my knowledge the subscription was cancelled, little did i know that multichoice was still charging me for the service for the last 6 months only to find this out on the 2 January 2016. I contacted multichoice on the 4 Jan and was advised that I send through a 5 month bank statement (NOT ON), I was then told that a team leader will call me back, which never happend, i call again on the 8 Jan, was then told i must contact my bank to do a reversal off the payment that was debited on the (2Jan) BY CONSULTANT THEMBA), why should i be doing all as this was an ERROR made by multichoice. I WANT MY REFUND!!!!! i Then spoke to the Team leader, Lucky Legodi, who told me the reversal of the amount will be done in the next 7 working days. SO I'M WAITING ON THAT! Thank you
