modem account dispute - no response

i have been trying to sort out a problem with my modem itimised billing account for almost 13 weeks now if not longer. i have had the same account with autopage now for several years and all i do is read work emails and answer them and sometimes read gossip coloums and the beeld. and my account has always been about R110 per month. then i get a early christmas gift from autopage and October 2014 the account is R1400. so i fill in all the forms to have vodacom supply me with an itimised billing of the data they say i used. i have had no response from autopage although i have phoned them about 12 times and sent emails like forever to try and get this info. BUT NO WHY LISTEN TO THE CLIENT / BULL **** I AM TIRED OF THIS. then i get an account for November and December 2014 that is almost the same amount as october 2014. what the hell is going on. <br> i do my job where i work with clients on a daily basis if i can do this and many others can then YOU AUTOPAGE CAN ALSO DO YOUR JOB. CATHC A WAKE UP.<br> <br> I HAVE NO PROBLEM PAYING THE ACCOUNTS BUT I WANT TO SEE WHY AFTER MANY MONTHS AND YEARS I NEVER HAD A PROBLEM AND THEN NOW FOR THE LAST 3 MONTHS THE DATA IS SKY HIGH. EXPLAIN THIS TO ME.
