Cannot get detailed July Account

I've been with Mtn for many years, with on & off overcharged billing. I decided not to renew my contract from July. I have been trying since end of July to get a detailed invoice from them.... I know once I view it, it will be obvious that Mtn owe me money. Customer care is useless.<br> <br> Another problem has arisen. I always do EFT payments to Mtn towards end of the month. I paid in September for my 3G and now get informed per email that I owe for September and October, when I've paid for September. I even attach a copy of the payment, but Customer Care is so inefficient that they don't understand what month I mean. So once again, it means that Mtn want an extra payment out of me!!<br> <br> Customer Care keeps going round & round in circles when dealing with a person & is of no help at all!!!!!<br>
