MTN Superflex routing issue

I have now been trying to get my Super Flex contract issue sorted with MTN for over 3 weeks, Package was deliverd and I can make calls to MTN and Telkom number, however to the rest I get the error "We are unable to route your call, please call your service provider"

MTN call centre is sending me from Pilar to Post without a solution,

None of the supervisors is returning my calls, tickets has been logged and closed without following up with me (the CUSTOMER) or the call centre agents just dont care or listen to their customer and just puts the phone down. Even instore, they just pull up their shoulders and say "Superflex is online only and we cant help"

Any one from MTN that can help me???
