Unhappy Customer!

I've been experiencing issues with my DSTV account in terms of amounts that I've been required to pay, I've noticed that they're higher than the usual amounts I was normally required to pay. I had Showmax for about a week, canceled it before the free trial ended but I'm still being charged for it and the consultant just keeps on telling me that it doesn't reflect on their side as if it's my fault. I'm on DSTV Explora Ultra & Compact Plus Subscription contract on price lock and was paying roughly R500 and something monthly as instructed my the SMS's that I was receiving and the DSTV app. I'm now faced with a problem of being charged high amounts of money and additional costs which were not disclosed to me when I started paying and I started experiencing this in December. I've been sending emails and calling but no assistance till this day, I haven't paid my DSTV in months hoping the amount will make sense but nothing! How am I being charged R1268 now?! I've been trying to cancel my subscription, pay whatever cancelation fee and sell my DSTV because I'm now really upset as I've been a loyal DSTV customer
