They delivered expired products, now they don't want to help me

I ordered a case of beer beginning of December. My order came and one of the 6 packs was expired already. Their personal shopper clearly doesn't know how to check expiry dates. So I phoned the customer care line straight away and they told me to email them photos and the expiry date. I did this on 3 December. To date nobody has bothered to come back to me. I have now phoned them again and been told that the only solution is for ME to drive 25km to the nearest store and see if they can help me or refund me for the 6 pack (R70). I explained that my petrol would cost more than that and that it is now holiday season, so busy roads, no parking, etc. etc. AND that Pick n Pay would be placing me at risk for exposure to covid due to there being so many people at the mall. Why can they not refund me online, after verifying my identity? And why do I, as a customer, have to chase them up to do their jobs AND run around trying to see if one of their stores can help me. It is their mess up, now it is up to THEM to fix it. Don't make me run around like kippie die ****. Just do your jobs properly.
