Being billed for a two contracts instead of one

Last year I started a contract with Telkom mobile. I initially app**** for the Samsung Galaxy S6 contract, but due to stock constraints changed it to a S6 Edge as the S6 was out of stock with them. This was done on the suggestion of the sales lady at Telkom helping me.<br> <br> When my first debit order went off, I was debited for two contracts not one. I immediately went to a Telkom direct store to report the problem, where they promised me the matter would be resolved. But then in December my account got debited for two contracts again. I once again contacted the Telkom helpline regarding the problem only to be assured they will credit me by the next billing month. They didn't, January I was debited once again for two contracts. So I phoned them again, got the same answer. <br> <br> At the end of February, they have at least canceled the contract and have stopped billing me for it. But the problem got worse! I now face a an early cancellation fee of R5,560.00 for the contract that they botched and I'm still not refunded! They are leaving me no choice but to stop the debit order to prevent more losses for me.<br> <br> The technical references for my case are:<br> ***6<br> ***8<br> ***9<br> <br> PLEASE HELP ME!!
