Incorrect Debits

Writing Review on behalf of my wife Natasha. Last year September we upgraded her contract which resulted in an increased fee due to early renewal (Fair Enough) After 3 months of paying +-R300 extra we were told that the fee would revert back to the normal amount of R498. Telkom then debited R729 without any explanation, The account bounced because my wife only left the correct amount in her account. We went in to the tablebay mall store and they apologized for the issue and said it was escalated and will be corrected. We were then not charged the following month because the debit order was canceled by Telkom. We had to then go in and pay manually at checkers PLUS a penalty fee which again was supposed to have been corrected. A few months later and every month they are debiting at random times extra penalties and the Website and App invoices are all different. We called in today and recevied another sotry that now apparently we have to manually pay again and a further R250 fee has been added. I dont know what more to do to have a sit down to explain this and have telkom own up to theri mistakes. The staff have no clue whats going on and have a new story every time.
