Going to be interesting to see what happens with my refund today. Just got 12 x 2l of Diet Cherry Cokes delivered today and sent 18 x 2l Diet Coke back. Told the driver that it works out better for me that way because I should get 18 x £1.85 refunded...although for some reason I've had random amounts of money refunded instead.
It's obvious that these drivers are pulling some kind of fast one, the last refund I got was £17.15 and it should have been £20.35 which was totally random.
If they are doing anything dodgy then that driver should have corrected things before he left, I said this after I signed for the shopping lol.
