Post bank sassa grant cards workers at west Street ShopRite are not helping anybody

I have terrible experience with the post office workers that Are allocated in Durban ShopRite to renew the sassa grant cards, they are not working, they let us to stand in the queue for 2hrs after that they said they are not working the system is offline they took our contact numbers and promised to call us, we waited for the whole week and they didn't call I decided to go and check on the following week and they said they don't have cards, it's been 3 weeks, they wake up daily to go and sit at ShopRite with post bank tables and press their phone until the end of the day , a lot of elderly and kids that are residing around Durban Central they never get their grant on September until now cause in the whole Durban Central it is only ShopRite west street where Post bank workers are allocated for nothing just to sit there and play Thier phones
