USELESS

In 2015 i took up a contract with Telkom which was supposed to end in 2017 Dec. monthly payments were made till the contracted ended upon request to cancel my contract in Nov 2017 i was adv that last payment would be in Dec & that cancellation was submitted. In DEC 2017 i go to the store in Mapoya Mall to confirm CANCELLATION & im advised its been SUCCESSFUL FF to Jan2018 i have a debit order that runs off , I ignore & reverse it. again in Feb another debit now i'm confused so i call them , im 1stly told that my debit for Dec 2017 wasn't successful which i query ^& prove through my bank statement , then i'm told the contract was only CAncelled in JAN 2018 meaning my calls to cancel & petrol to Mapoya was a waste of time & money, not only that the call center agents clearly don't know what they are doing. i have now had bank charges for payments & reversal, i'm also paying for calls being made to them to resolve the issue. TELKOM PLEASE ADVISE WHAT I MUST DO SO THAT U CAN LEAVE MY HARD ERNED MONY ALONE!
