Unexplained unauthorised debit!

It's a shame that one has to rely on a platform like this to get any decent feedback. I moved into an area that had no cell c fibre, and could not move with my M2M fibre service from cell c. I was debited a large amount of money that I have no explanation as to what it is for. I have emailed and tried to get assistance to no avail. Please can you explain why I was debited R3000 plus. Can I just get a breakdown of what added up to that amount. Please don't waste time explaining claw backs and hardware charges, I understand that as that's all I hear from your advisors. What I would like us a full breakdown of what I was charged for.
