Renewing Contracts - Billing Mess

I upgraded two of my contracts with in Feb 2015 at the MTN Store in Morningside. I was advised by MTN Corporate to do the upgrade at an MTN Direct Store because they did not have stock of the phones I wanted. They assured me that the Direct Store would apply my normal 18% discount. In a nutshell, I need the following to be corrected on my two contracts: <br> o Removal of the upgrade fee<br> o Process my corporate discount of 18%<br> <br> I've been trying tirelessly to try to correct my billing but i am struggling to find someone who can assist. I've spoken to Ryan Findlay, Jason Loyd, Clayton Codd, Gavin Goncalves, Dushen Naidoo, Phinda Mankga & Vincent Rangwana. No one seems bothered to help me resolve this. I'm fed up with the lack of customer service, One would think that i have 4 contracts with MTN and been a loyal customer for 7 years that they would take my business seriously. Vodacom/CellC sharpen your customer service and ill gladly move over to you.
