Incomplete order received

I placed an order on Friday 4th of March, after I collected from the driver I noticed there were items missing, I tried calling their number ***@18:13 but no one to answer, it was after hours, so I contacted the store straight where the order came from Pick n pay Killarney and they said that they can't help me only ASAP can give instructions. So I waited until Monday to contact ASAP because they are not even answering emails, I contracted the store 1st I came across to a very rude consultant who drove the phone on my ears, then I called again, second consultant said she will contact me and advise of the outcome, next thing the ticket was completed without any resolution, I called again and the consultant promised to call me back till now no one has contacted me, please refund my money and I don't want anything to do with Picknpay ASAP anymore.
