My contract on number 082 964 3652 expired in November 2017. I cancelled the contract on 2 December 2017 and switched the number to prepaid after way too many issues with Telkom contracts.
After opening numerous cases to inform Telkom that I am STILL being debited monthly for the cellphone contract, I am still receiving invoices to the full amount, even though my phone has been on prepaid for almost 3 months!
The incompetance never ceases to amaze me. What you are doing is illegal and I better be reimbursed for every cent illegally debited from my account. I have lodged a case with the NCC and won't hesitate taling further steps should the issue persist.
