Incorrect Billing

Good day, <br> <br> I have queried my account 2 weeks ago, and 2 days ago I only got an answer, but still it didnt solve the problem.<br> <br> Since upgrading my contract with MTN in January of this year, I have been billed incorrectly, and I would like to advice MTN to rectify this on the following account number and to credit the account accordingly.<br> <br> N*** , ***<br> <br> Firstly according to Bongi's response the H/W Fees must be credited, please note this is since the contract was ceded or bought over from Nashua Mobile that this must be done.<br> <br> Then according to your consultants at the franchise the PROMO FEE of R292.98 must be credited, I have been charged for this since the upgrade in January, so please credit this amount.<br> <br> Kindly note that due to MTN's lack of customer service and assistance, I was forced to port to another Network, that can actually supply customer service. I have had enough of staff at franchises that doesn't want to assist there customers, as well as your client service centre 808, that don't know what they are doing. <br> <br> Please advice me once all the credits have been passed so that MTN can refund me my money.<br> <br> Thank you.
