Account issues unnecessary

Last week thursday my Dad's account was suspended. After 3 days of attempting to make contact with the call centre and logging online queries, i could not find anyone to even answer a phone.<br> He then went into the MTN Richards Bay branch, where he was told that the data balance query on his modem was read incorrectly and that an amount of R2000.00 was required to restore his account.<br> This was paid for on saturday and accounts were restored. Today the accounts are suspended again. The modem was not used the entire week and the phone is on a top up contract.<br> <br> If he could please be contacted urgently to explain how this can happen AGAIN!!!
