Billing issue with no result

As a client of Autopage for the better part of 15 years, and with 2 phones on my existing contract, I <br> am extremely upset at the manner in which Autopage is dealing with a query <br> from November 2014. I obtained an extremely high bill from the usual R 4000 <br> pm to over R15 000 for apparent data usage. Since November I have queried <br> this, and for unknown reasons I have never had this proven. My phone is <br> currently suspended daily, and this is my work phones as estate agents. We <br> are religiously told we are in the wrong, and have been handed over. Every <br> month we pay more than our \contract"amount"
