Outstanding balance on my telkom account

In 2018 I app**** for a cellphone contract that was a tablet with 2 simcards, unfortunately aafter a few days of receiving it I found it faulty. I called the agent who assisted me with the application and informed her that the phone was faulty, she advised that she will send people to collect it, a guy from Ram couriers came and collected it and that was in 2018 November. Nobody bothered to inform me of what was happening, no debit order ran on my account and I concluded that the contract has been canceled. I recently encountered some problems and visited capitec Bank to borrow money and I was told that I'm in arrears with telkom for about R5000 and something. I then contacted telkom to request a letter proving that the contract was canceled, only to be told that it was never canceled and I'm liable to pay the arrears. Now instead of the tablet I know I'm informed of 2 devices ( hauwei p smart) that I know nothing of and I'm told that I have to produce a waybill that Ram gave me when they collect the device or there is nothing they can help me with.

Please assist as I nolonger know where to go for assistance
