Disgusting customer service - PnP ASAP

Placed an order on 25/04/2022. Box of 20 sachets of cat food arrived damaged, open and missing 4 sachets of food. 2L bottle of oil was leaking oil all over the packaging. Since then I have called the call centre, sent picture evidence of the issue, tweeted multiple times, mailed again and I get ZERO feedback. The lady in the call centre I spoke to said she would arrange for the remaining sachets of food to be delivered and a new oil...2 1/2 weeks later and still waiting. I even have a reference number, not that appears to matter.

This is not the first issue with this app and once again the customer service is beyond awful.

So PnP basically seem to think it's ok to charge customers for stuff they don't get in their orders, and then provide less than zero customer service when it is queried.
