EXORBITANT BILL CANNOT BE EXPLAINED!!NO RESOLUTION

In May 2015 my cell number was blocked and the reason given was, excessive usage, and I was informed by Altech Autopage that my bill was R4200. I lodged a formal query with the Hillcrest branch and was advised it was due to internet usage. I explained that I never use my phone for the internet and requested a report showing what sites I had apparently visited. Do date Autopage has not resolved my query and yet have handed me over to NuDebt Management (Pty) Ltd and demanded the now R5247.97 owing.<br> At the time of lodging the query at the Hillcrest branch, there was another customer with the same problem and she advised me that there were apparently 90 other queries and complaints of this nature.<br> Another issue I have is that for the past five years or more, my bill averaged R350 per month. If Autopage could block it at any point for excessive usage, why did they wait until it was sitting at R4200 before they blocked it? Please help as I am not prepared to pay this bill and believe this to be a trumped up issue of \usage"."""
