Pick n Pay ASAP! (Formerly Bottles App) - WORST SERVICE!!!!

I decided to use the Pick 'n Pay ASAP! App today. Placed an order at 10:05, got a receipt stating order was delivered at 10:34. I always double and triple check to make sure that the delivery address is correct. Once I placed the order, suddenly my delivery address changed to 170 Frikkie de Beer Street, Waterkloof. When you look at the store details, it's exactly the same as the delivery address!!!! The funds have been taken, I am still sitting without my products at 14:55. I have phoned the ASAP contact centre twice, to which both times they say they will give me feedback. It doesn't take an hour or two at a time to get feedback on what happened with a delivery. This is THE WORST EXPERIENCE with a delivery app/company. Now, let's say that they do find my order which has been mysteriously lost, they can't deliver it after 16:00 as I leave work at that time. I'm so extremely annoyed with the service and how stupid this whole process was. Absolutely pathetic.
