OVER BILLING *****ING

I cant belief how many times must i complain about my account and yet if i stop my debit order they will suspend my account for their mistakes.<br> Over billing me with R74.19. no one cant tell me the reason for this. my account should be R769.00 per month except if i make additional calls.<br> <br> I reported it and got ***. they are good enough to ignore their customer and just like MTN will take you money.<br> <br> Let see if they going to ignore a customer still.
