Blaming IT issues for bad service.

I am on a normal consumer contract with MTN, I have been trying to change my consumer contract to a business contract for the last 5 weeks now. I first went to the MTN shop in Mall @ Reds in centurion where they just said to me they cannot do it because of IT issues with MTN. Then I went to the MTN shop in Centurion Mall where Kopano did everything in his power to help me, but because MTN cannot sort the IT issues I am still unable to do this. Losing a customer very quickly now because of IT issues where old and new systems does not work together.
