I have received a bill of R3529, R5639 and now in July of R5594 from Autopage. I went in to Autopage and complaining about my bill and phone them to, they said it will take 14 working days, and stopped my debit order, after 20 working days and receiving another 5 grand bill, I phoned custermer service and said they haven't looked into it. No one has phoned me or mail me regarding my bill. They are useless, and I won't pay anything. How can my bill go from R99 to Over R5000 in 4 months. They account department need to wake up! I am waiting to hear what they have to say!
