Worst service and customer experience ever

Our contract expired on 17th December 2021. Head Office phoned my partner twice to confirm this. We went to Eastgate branch on the 18th of December. Leo from the branch gave us a new contract for more gigs with the same monthly payment. On the 11th of February 2022 we received an sms saying there an AMOUNT outstanding. On Sunday the 13th of February 2022 we were told by Eastgate branch that the contract was never CANCELLED which was Leo the consultant had not done. Telkom also charged for a debit order which should never have gone through a unpaid fee of R202.70 which is almost more than debit order. Leo and his Supervisor Lerato confirmed once cancellation done we will owe Telkom nothing. Accounts department who have been emailed don't answer emails either. I have to keep phoning Leo everyday 3rd day has not done his job. Sorry Telkom we will CANCEL this contract due to poor service, no feedback totally disgusted. We will take this matter further, as my partner has a good credit rating and Telkom not going to mess that up
