Autopage does not care about their customers

I have had an account with autopage for 3 and half years now, and last month my account was blocked I went to the store to report it but was told my account was up to date and they will open my line, but it was never opened. I called with no assistance. Month end I got a bill of R3400 which is 10 times more than what I pay. I went to log in a dispute on my account which was still blocked and is still blocked to this day but then again I received a bill of R7100 which means I was billed an extra R4000 in my account which for the whole month I have never used. I went back to the store and the lady tried to call account as my dispute isn't resolved yet after 5 weeks of logging it. the accounts tell me that I will have to pay the money as it is data used, they don't care to even follow up how an account that was blocked is still active and try to work with me to resolve the matter. instead I got attitude.
