And it continues

Further to my previous complaint and the pathetic answer from MTN, not answering any of my questions, the saga continues. Despite my account being capped on 2 June 2015 and confirmed so by the call centre today, my bill for this month is R7556, 86 and my credit limit R4125???<br> <br> I called the call centre to query and was cut off 3 times and eventually spoke to a Dillan Clayton in CPT who actually laughed at me and refused to put me through to a manager, before cutting me off too. He claimed that I ran that bill up before my account was capped on 2 June but the billing is for June??? A day after MTN deducted R9819,85 from me on a bill that consistently ran on a R2500 per month bill???<br> <br> What can I do to resolve this????
