Shocking service from MTN

I did my mtn contract upgrade at Istore the Glen, however they cannot process it as MTN has not loaded the package they have offered me onto the system. I did my application on Monday 14 Dec, this is a Christmas gift for my son. Whenever the staff at the istore call for assistance they are passed from pillar to post. Bottom line I don't have my new IPad and it is Christmas Eve tomorrow. Trying to call MTN is a waste of time, useless is what they are. How can they give deals or promotions to the istore then not load it to the system. Shocking customer service. I cannot do my upgrade at a MTN store as they do nothing t keep 32 gig iPads anymore. So I was forced to go to the istore. I cannot believe that a large company like MTN cannot get their act together and solve this. Worst service ever.
