In September i asked telkom mobile to change my account number to the new one and they advised me it has been changed I then waited for the debit order to go off in October and it did not happen they even tried debiting on the 24th when I advised them or should be done the last day of every month I called in the 30th of November just to come across that it still hasn't been changed I even called in numerous tomes before To ask them to change it and I kept getting good it has been changed now I'm left with paying over R2k manually which I didn't budget for I'm extremely ****ed off and not happy now I need my account to be active for work purposes and it's suspended for another month which means my payment for December will be R3k that's the invoice I got via email
