TELKOM ****ming people to pay for accounts that were closed and paid in full years ago!

My brother closed his telkom account more than 2 years ago. In order for him to close his accounts he had to settle any outstanding amounts in full. About 8 months later they called him and informed him that he need to pay R1 200.00. This now also effected his credit score. Several emails were sent with the proof that he paid his account in full and his accounts were closed. He now had to do a sim swap today, but they refused to assist him because they claimed that he still owed R600.00. Having had enough of their uselessness he offered to immediately pay the R600.00 in store just to get his sim swop. This also was not possible because they claim that they do not receive payments in store. He now need to call the call centre, enquire how to pay them, then make payment and have to wait 3 days and only then will he be able to do the sim swop. What a useless bunch of people. No wonder Telkom is rated the worst mobile company in South Africa. Everyone should rather just stay away from them and make use of people who are willing and able to render professional service.
