MTN Billing Error

I upgraded on 2 October 2015, which included the My MTNChoice 350 without a phone. My limit was also set to zero and my accounts was up to date at the time of upgrade. My account should be R369.00 (Inclusive of VAT) per month.<br> <br> My account for November 2015 realized R2383.77 (inclusive of VAT).<br> After visiting my local MTN shop and going through my invoices I found the following.<br> <br> (1) No Credit Charges that makes out the complete MTNChoice 350 contract has been uploaded for November 2015. I am being billed R609 for my normal account, which should be R369. This is obviously wrong.<br> <br> (2) An additional usage charge of R1774,77 has been billed for November 2015. This is not possible because my limit is set to zero and I cannot be charged on out of bundle rates unless I upload airtime with my debit or credit card.<br> <br> Please correct my accounts.<br>
