I've given items back to Tesco drivers for a variety of reasons. Such as an unacceptable substitution, a damaged item or the wrong item delivered......as well as an occasional change of mind (usually because I forget to edit it off the order). Sometimes the refund comes through automatically, other times I've had to make a phone call to get it.
If I don't notice the damaged item or incorrect item until after the driver has left, it's always been refunded without quibble when I ring (and I get to keep the item). Is it worth ringing for a refund if there's a rotten apple in a bag of apples? Maybe not, if you're too busy. But if a large bottle of the wrong laundry detergent is brought, I would definitely be ringing.
