The bad service and bullying continues

So DSTV fixed the double billing issue i complained about and event sent me an SMS to say how much i will be debited, they also rectified this on the mydstv app only just to make a fool of me. they went ahead and double debited me last night. i am literally in tears. DSTV *******ly took my money and now they want me to send them an bank statement when they can see and have acknowledged that they can see they mistakenly billed and took my money. who will save us from this bullying from DSTV. i am now spending money on phone calls, they put me on hold then i have to call again plus the money they took was for my home Laon so now that has to suffer or i must now make plan. i am suffering for being a loyal customer to DSTV
