Post bank should have not canceled all the sassa card at once.

So Post bank decided yo cancel all old card even ones that are not expired and then the can't handle the concequences. As expected people are flooding the Pickn Pay outlets, but their system is slow there's one consultant at Maponya mall with a queue of over 100 people waiting tomake their cards, they claim they(consultants) dont have cards, why such an inconvenience why bite more than you can chew? My card is not expired just canceled now I'm coming here for the 3rd time only tobe cut off, due to system nd 1 consultant.
