Large supermarkets and customer care

We use TESCO for a once a week home delivery. If anything goes wrong like finding a too short date which hasn't bee pointed out or finding mouldy fruit thr customers service as been superb. The phone has been answered in a few rings, the person I've spoken to has always been efficient, polite and has provided an immediate refund and apology. Can I add a problem is rare.
When they couldn't deliver because of circumstances beyond d their control we were informed quickly, a £10 voucher against our next shop was given a d a delivery the next day offered.
They even reopened the click and collect when either of us was well and I foolishly booked a click and collect instead of home delivery. When I rang to ask where my delivery was they politely explained and said they would ring back within 15 minutes. They had spoken to the store manager and was told if I could say a time within the next hour they would have my groceries ready at the click and collect (which had closed a hour befire) or they would deliver the next day. I have no complaints at all.

I always complain via the app l ordered on (not sure if all have this facility). Without exception I've been refunded to my satisfaction.

My DD recently phoned Tesco about mouldy fruit and a wrong item in her delivery.
Got through quickly & helpful staff provided refund promptly.

I just saw this on Facebook, tho.

I read recently, not sure if on GN or not, that a lot of companies are just not interested in Customer Care any more.
