Worse Service from Pick N Pay Mall of Africa & their Bottles App... Never use their app to order groceries

Worse customer service experience, I ordered groceries over R500 from Pick n Pay using their app 'Bottles'... I monitored my order from the store when the driver picked it up till it said driver is on the way to me. I have put in all my details, the correct address, with Block and unit number for my apartment. To my surprised the app updated that my order has been delivered... No order arrived at my door. I'm so disappointed. I immediately called Pick n Pay Mall of Africa, a lady answered... I explained what had just happened with my order. She acknowledged that my order was made & had been picked up by the driver (she mentioned the name of the driver) after that she couldn't assist me she said she will call me back & took my number but no one ever came back to me to update me what has happened to my order. Their app is the worse... I also reached out to them about my order but couldn't get any help besides an automated chat reply... About investigating & getting back to me. I'm very angry & disappointed with Pick n Pay & their app.... I couldn't cook supper for my family.. No grocery, nothing.... & they haven't gotten back to me even now.
