Unfair Business Practice / Smart Shopper Rip-off

Since December 2017 , i have been trying to redeem my hard earned Smart Shopper points.The Pick n Pay App available in the Play Store is none functional as it gives errors. Then in January l received an sms to say my points were expiring. I tried redeeming these points but the App was not working, i tried in-store and smart shopper card still did not work. Then those points expired. Now l received another sms saying l points will expire, l have been in store to redeem points and it still gives me errors. I have called the call centre about 3 times and was told issue is being escalated and account will be reset. There is still no resolution to this issue. Pick n Pay please stop ripping-off customers.Fix The App, Fix my Account. Taking my points amounts to unfair business practice and misrepresentation as these issues are Pick n Pay's fault.I earned those points it's time to pay up Pick n Pay.
