Pick n Pay ASAP - so ridiculous.

Pick n Pay asap was so great at the beginning but have finally lost me as a client after numerous disappointments. I even recommended them to family and they failed to deliver a complete order?! How difficult can it be to pack an order and make sure everything is added?? It's so embarrassing. The app glitches and tells you the driver is at the store then it never updates again and next thing you are notified that the driver is here. The driver then does not contact you, or ring the bell for your apartment - they don't even wait 5 minutes and leave again with the order and then send a notification of "failed attempt to deliver". It's so ridiculous and stress full, then getting hold of customer service for the ASAP department is such a hassle, sometimes you get through to the call centre and other times you have to email - emails only get responded to 3-4 days after you have opened a query. If they short deliver you will only be refunded in 1-2 weeks, if you're lucky. What type of customer service is this? How are we supposed to use a service that does not even work?
