SERIOUSLY UNHAPPY MTN CUSTOMER

MTN has recently moved over to a new system without doing the due diligence of testing the system to make sure it works. EVERY SINGLE MONTH I have to call the call centre for someone to try and retrieve my invoice. The staff have not been trained on the new system and to make matter worse if you finally get to speak to someone, the system is hanging and they can not help. WHY CAN YOU NOT SEND INVOICES AUTOMATICALLY, MTN? YOU MANAGE TO TAKE THE DEBIT ORDER WITHOUT FAIL EVERY MONTH? I have spent a total of 6.5hrs on the phone (most of it waiting for an agent to answer.
