Pick n pay bottles app

I ordered some things on the asap (pick n pay bottles app) mind you this was not the 1st time I ordered on the app. When the delivery was done, the guy had a friend with him who was on the phone, I asked for delivery note which was not there and normally I get that... Got into the house and checked the items as per my order and the were 2 x 5lt wines which were on special that were missing. I immediately send an email and auto response said I'll be contacted in 48hrs, it passed no response I send another email and same response... I have lost count as to how may emaims and phone calls I made. To date nothing is coming forth am so tired and more over disappointed
