Still NO Feedback after visiting 8 times!

I'm with Mtn since I could afford it. I recently paid up my 2nd 24month contract and the thanks I get? \Sir, you owe the legal department R1890\" <br> <br> After a whole 8 visits, I still do not know why I owe this amount and I sort of gave up trying to find out.<br> <br> As if that's not bad enough, I need to know this information to pay my new found debt. If I don't pay it within a month's time, I get billed another R250 <br> <br> How's that for interest in a situation that should be blamed on the constant delays while waiting for that \"promised phone call\" - Mtn Never calls back..<br> <br> A nice reason for the money I owe, a place to pay(if justified, preferably at a Mtn store), reactivation of my sim card and finally I'd love to end my contract at Mtn"
