Billed and failure to get details as to what the billl is for exactly

<p>MTN have over charged me a amount which I do not understand how they got to it. I have been told that I awe +R990. When I try to ask that MTN provides me a breakdown of why they came to this amount, all I get is that I awe.</p> <p>All this issues started when I my MTN account was *******ly upgraded which I had logged with MTN + the SAPS, this was resolved but I still have a crazy bill left with me when I ask what exactly are the charges for, I get no response.</p> <p>At one point I was told that I did not pay in 2014 an amount of R570, which I buy the way I was not told thanI was notified on the week of the 21 November. I sent MTN the prove of payment(debit order payment prove and MTN'sown invoice showing that I paid) but they then just came back to me saying I owe. yet I again never for what exactly.</p>
