PnP ASAP ridiculousness service

I bought my groceries on pnp ASAP and now the store that delivered my groceries are saying that they are unable to assist me with a return. They sold me spoilt milk and my friend received tinkies with expiry date 24th November and 27th November during the black Friday specials. I was told to phone the ASAP call center then I am put on hold. Pnp should have thought of this ASAP better before rolling it out without better contingency plans.
