Vodacom simcard still not activated after porting.

We purchased a new iphone on wednesday(25/11/15) from vodacom and requested to port a prepaid simcard from mtn to the vodacom contract. We received two sms's stating the porting has been approved and we should visit a vodacom shop. Friday(27/11/15) we went back to the same vodacom shop and the consultant said they'll call us back in 30 minutes when the simcard is up and running. It is now saturday(28/11/15) and still no activation,old mtn simcard still works,new vodacom simcard in iphone says no service and did not receive any call/sms from vodacom on the porting date or what's happening. We called into the call centre endless amounts of times only to be told to relax,there is nothing thhey can do. Should I be regretting this move to om because right now,I really am.
