MTN Billing Error

I upgraded my MTN contract on August 2015. The upgrade included only a MyChoice 350 2 year contract without a phone. Furthermore a limit of R0 was also set-up on the day of upgrade and have been on a debit order for the past 6 years.<br> <br> My account should be approximately R369 per month, but from my upgrade, my account has been approximately R610.<br> <br> By following up with my MTN shop and the call centre as well as going through my online statements I eventually identified the problem. The problem is that all items for my contract is loaded, but no discount items that make out the complete contract and thus the higher account.<br> <br> The following reference numbers are applicable:<br> ***<br> ***<br> ***<br> <br> Please correct as soon as possible and credit my account accordingly.
