NO NETWORK CONNECTION

So I have had an ongoing query with Autopage/MTN over the last 2 months regarding why I was being charged for data that I had never paid for before. Finally, after 2 months, and 2 more inflated invoices, someone EVENTUALLY explains that I had previously had airtime carried over which was supplementing data costs. This was used up 2 months ago and Autopage started charged me an exorbitant R2 per 1MB out of bundle. That is disgusting. If someone could have told me that 2 months ago, I would have added on a 2 GIG bundle which would have saved me thousands!!! Anyhow, no one cares! So now they collected an unauthorised amount off my account on 1/7/2015 but my line was suspended on Friday 3/7/2015 and has not been reconnected since. I have sent copies of bank statements and proof of payment, and still no network or connection a week down the line. Couldn't they give me the benefit of the doubt? I have provided proof. I can't go anywhere, I'm bound by a monthly contract, you will get your money one way or the other!
