ASAP means nothing to Pick n Pay - empty promise!

Pick n Pay ASAP doesn't even merit a one-star score! I tried it today for the first time, placing an order that the app shows was accepted (and charged to my card) at 14h46. The delivery time was predicted to be 15h30-16h00. Just after 16h00 the app changed that to 16h00-16h30. When it hadn't arrived by 16h30 I started phoning the call centre but no agent answered the call and eventually I had to leave a voice message, No-one got back to me and the app then changed the delivery time to 16h30-17h00. I then resorted to sending an email, which has also elicited no response. When the app changed the delivery time to 17h00-17h30 (and I was needing to go out urgently, but also needed one of the ordered items urgently), I phoned the call centre again and got agent Shamila. She said the first driver assigned had a "problem with the bike" and no other driver had yet been found. When I insisted that I receive the goods I had paid for, asap, she contacted the driver department then called me back to say a driver had been located at Nicol Pick n Pay in Bryanston (approximately 15km from me). She could not say when he would deliver the items so I'm currently stuck at home waiting helplessly for them and having to rearrange my plans yet again. Absolutely not good enough, Pick n Pay!! I'll revert to using Checkers Sixty60 which delivers reliably, usually in less than 60 minutes, and keeps customers informed all along the way. The ridiculous ASAP app has been saying "We're wrapping your order" since 14h46 and it is now 17h15 and the delivery slot has been changed again to 17h30 to 18h00. Useless service.
