Store Payment Allocation & 30GB Data not allocated

I am still waiting for a payment that was made in the MTN Northgate store to be allocated to my account. I have called the call centre multiple times (both in MTN stores and the MTN call centre) but still have a payment of R741.20 that has not been allocated to the account. I was then debited for the amount the same amount. <br> <br> On renewal of my contract in January this year, i was meant to have 30GB data allocated to my contract as per the special running at that stage. After more than 3 calls to the call centre i still have not received the data. Its a pity as i generally sing MTN's praises to other people moaning about their providers, however i am not sure now. <br> <br> This unfortunately is after i have sent the required information through to multiple different people who all promised to have it resolved.
