Customer complaint

I have been incorrectly billed for my account since November 2013. I only realised and started quering this when i received a bill of R21000.00 in April. Since April there has been very little effort from their part to resolve my query. Up to now, all i know is that its is confirmed that there is a second sim card under this contract which i did not ask for. I have been pushed from pillar to post with no success. Brian Maleka (Supervisor at Autopage) forwarded my information to their ***** department more than a month ago and no response has been received as yet. I even opened a ******** case at the Jeppe police station and they could not even provide the police with the relevant information required for this investigation. All i ask is that every cent which was accrued by the 2nd sim card be paid back to me because my account has been very high at times. I did not question it as i am a business man and thought that maybe it was normal for my account to be at times R11000 or R9000.00 per month.<br> Please knoe that this matter will not be put to rest unless my money is paid back. This amount to *****ing from your customers, and i have been a loyal customer for over 6 years.<br> Many thanks
