INCORRECT BILLING/BAD SERVICE

I took a WIFI router contract via the telkom , then the HORROR and NIGHTMARES started . The router had no connection due to the area connectivity , I then requested telkom to cancel my contract which was tedious and daunting . I ended up going to the Glen branch to solve the issue , I was informed that it would be sorted and my router would be collected the very next . true to their word the router was collected it then told me the contract will be cancelled . WOW what a load of **** I was being fed , come the 25th I was debited with endless calls day after day Telkom could not resolve my concern. instead I was told to cancel the contract which when I tried "NO CONTRACTS/NO ACCOUNT" appears . PLEASE EXPLAIN TO ME HOW EXACTLY AM I SUPPOSED TO CANCEL SOMETHING WHICH DOES NOT EXIST BUT I AM BEING DEBITED FOR IT . I reversed the debited and was charged for TELKOM's mess with no compensation whatsoever and then ANOTHER DEBIT ORDER .LETS NOT EVEN TALK ABOUT THE CALL CENTRE WHERE YOU NEED TO EXPLAIN YOUR CASE TO EACH AGENT THEN HOLD FOR 1-2 HOURS , NO SENSE OF URGENCY AND CUSTOMER SERVICE . TELKOM IS A PATHETIC BUNCH OF CLOWNS
