Unstable billing on my cellphone contract

I had a cellphone contract with Autopage since 2010, it was a 24month contract with an option to extend to another 24months. Around last year February/March I started receiving different billings on my statements each month, I quarried to Autopage because I had a fixed instalment to pay (R290), not fluctuating instalments. I was then sent from pillar to post, I was never given a straight answer or something in writing. I told them I won't pay until I get the right corrected statement.<br> <br> Then my online My-account login site was blocked and a couple of months after I got an email stating that I have to pay for my contract or they will begin with legal proceedings. I still requested clarification on the billing system they used and the corrected statements but I never received that. But Autopage continued charging me for services I was not using because my phone was blocked. <br> <br> Last week I received a call and an email from VVM attorneys on behalf of Autopage telling me to pay a sum of R14000. I'm now confused and surprised about this huge figure since no-one from Autopage responded to my requests. <br> <br> Peter please help.
