TIRED OF PICK N PAY!!

I ordered from pick n pay (CAMPUS SQUARE) via Mr delivery app yesterday and they cancelled my order cause the driver wasnt able to deliver and they also didn't reverse the money but put it back in the wallet only after i called to enquire what was happening. My issue was that they cancelled instead of allocating a driver with a car or notifying me of that. Today i ordered again with them around 9:00 order was accepted 9:35 items picked by 10:10 and im still waiting for my order i cant even track the order cause nothing is happening on the app. I tried their whatsapp line no help there i have been calling their customer line since morning cause my order was suppose to be delivered around 10:33 but nothing has happened and i cant get help or get through to anyone. The service is horrible
