Not substitutions. I've had (separate occasions) -
6 bags of cat litter when I ordered 1.
2 blocks of cheese when ordered 1, and a random multipack of crisps I never ordered.
A massive finest pizza (on the day I was starting a diet!!), didn't order any pizza.
36 (!!) Muller Rice pots and a pack of Clementines. Neither ordered, although there were a lot of items missing from that order so maybe it was a 'sorry'
.
Never been charged for any of these nor do they appear in the order summary.
Anyone else??
