MTN HORRIBLE SERVICE - MV***6 [#***]

I made an application for data sim card and finally received it a week later. I am now patiently waiting for the sim card to be registered on the network for 3 days. I called a store and they advised I need to go to a MTN Direct Store to activate the sim card - why wasn't I told this when the contract was approved? This is **** service. I want this resolved ASAP - otherwise I'm cancelling this contract. You would think in the current economic conditions MTN would jump at new business - clearly they are and don't give a **** about after sales service - in fact there is no such thing as after sales service as they take 2 days to reply to e-mails & the 135 is useless because none of the options available are what I need help on!
