Frustrated with pick n pay asap

I've counted a total of over 15 complaints I've logged regarding the very same order and it's been over three days now, literally. I placed an order on the 5th of February. Firstly it took well over an hour just for the order to be attended to. I then contacted customer service because I didn't understand close to two hours passed and there was literally no change on the app. Customer service tells me a driver has been deployed yet the app shows that "they will get to my order asap". Finally, it says the driver is on the way... I go downstairs and wait so I'm there when said driver arrives. The app says he's there and he was not. He then calls and says he's here and I tell him I'm outside so that's not possible. Turns out he was down the block so I now walk to him to get my stuff because I'm irritated by the long wait and now this new inconvenience. Now, the app showed I should have recieved three pick n pay paper bags and I only received two which I took pictures of as well as well as the contents. I logged a complaint regarding missing items and when I tell you I've been going back and forth I kid you not. It's been three days, three. I spent hours yesterday trying to get assistance to no avail. They claim the driver left the store with the items and I told I them I only recieved two bags AND the fact that he scanned or took a picture of whatever they do when delivering so there's proof he delivered TWO bags so why not follow up with him?!. I tried to get help using all avenues. Email, the app, WhatsApp, Twitter and now this. The order was ridiculously late, the driver wasn't even at the right place plus a missing bag but I have to chase them just for feedback or correspondence. How I wish we could post screenshots here. MIND YOU, the day I complained I was told I'd receive an email confirming my refund in 24 hours. Then silence. I followed up not even for the refund but just to know what's what and to get feedback since they claimed they'd reach out and it's been three days of me chasing them only to be told story after story. I spent close to R600 on this order so I reckon I should at least have received some courtesy for a late delivery, incorrect delivery address AND a missing item. Goodness.
