Excessive bill for data i did not use

I have been an Autopage customer for approximately 8 years now. One of the contracts that i have is a data contract. I pay a fixed monthly fee and you provide me with 2 Gigs of data.<br> Since the inception of this contract i have never exceeded the 2 Gig data limit.<br> This month i received a bill for over R4 000. When i queried the account i was told that it is a data contract and the implication was that i was at fault. When i suggested that you look at the history of my account that you would see that it is unlikely that i incurred these costs you promptly cut me off.<br> I have tried repeatedly to resolve this issue with Autopage customer service but it appears that they are not interested in entertaining my request.<br> This is an appeal to somebody in authority at Autopage to see me as a valued customer and not just another complaint. I feel that as a loyal customer for many years that i deserve a little more respect with regard to my concerns. Please just look at my usage history and ask yourself if you honestly believe that i used all that data in one month. If i was one to abuse my data i would be doing it regularly not just suddenly. <br> Is this really how you treat loyal customers
