REFUSAL TO CANCEL CANTRACT & ABUSE OF POWER

I TOOK UP A CONTRACT FOR MOBILE WI-FI WITH TELKOM IN APRIL 2019. HOWEVER, TELKOM DELIVERED A RESIDENTIAL WI-FI ROUTER. I THEN CALLED THEIR CALL CENTRE AND WAS ADVICED TO TERMINATE IT (CONTRACT) WITHIN 7 DAYS. I CANCELLED THE CONTRACT AND WAS GIVEN THIS CASE NUMBER – ***7. IT HAS BEEN OVER 3 MONTHS SINCE I CANCELLED THIS CONTRACT AND IT HAS STILL NOT BEEN CANCELLED, DESPITE A COUNTLESS TELEPHONIC AND ONLINE REMINDERS. ON TUESDAY, 16 JULY 2019 I REVERSED MY LATEST DEBIT ORDER SINCE TELKOM IS BLATENTLY REFUSING TO CANCEL MY CONTRACT. THEN TELKOM WENT BEHIND MY AND APP**** FOR A "NAEDO DEBIT ORDER" AND STARTED DEDUCTING R249 DAILY FROM MY BANK ACCOUNT - SEEMINGLY TO DISPLAY THAT I AM AT THEIR MERCY AND THEY CAN DO AS THEY PLEASE WITH MY BANK ACCOUNT!!
