Tbh during and after Covid we did a lot of click and collect with Asda and I’m not sure if it’s the same now but anything you queried, ie dates of food, or didn’t like the replacements they provided you could request a refund on the app, and it was instant (and you kept the item). Not that we took advantage but we had some decent freebies, meat we needed to freeze rather than keep because of the dates rather than in the fridge and a wine they swapped which wasn’t the best (but still drunk).
