Missing Items and Wrong Item

Used the Mr.D app for my Pick n’ Pay delivery last Sunday. Two items were missing and one item was the smaller sized bottle than what I paid for. I logged a query on the app and had a reply to send a picture of the incorrect bottle size for them to sort out my complaint. That was 30 March and I still haven’t heard back. I sent a follow-up query yesterday (1 April) and again today (2April) and still no response. That is over R100 worth of food that I am missing that Mr.D and Pick n’ Pay have ****** from me. And that doesn’t even include top delivery and tip that was paid. I just want what I paid for! I just don’t understand why this query was dropped and is just being ignored. Absolutely appalling service and theft by Mr. D and Pick n’ Pay.
