Telkom.....bad bad service

I have been a customer of Tellom for a couple of years. Recently I changed to a different bank, I contacted them way in advance and wanted to change my banking details with them. According to them the new account need to be 3 months old before they can do that .in the meantime they charged me R200 for debit order that did not go through on old bank account, and even though I paid my account on the app, it caused the one account to be in credit and the other kne owing double the amount. I went to their branch at Mimosa Mall and the lady there changed my bank account details, and said it will not work yet as the account have yo be 3 months old. Again I paid my account via the app, and once again there is a ****** up which caused my number to be locked. I paid the R160 that is credit on the other account, at Shoptite and still my account is locked. Whenever you try to use the app, the function is not available or system is off. This is the worse service from a cell provider I ever encountered. When I phoned Vodacom to change my account details, it was done immediately and no hassles. My honest opinion of Telkom is that people should refrain from using them as service provider as this is totally the worst service ever.
