Ordered a McDelivery including a Deluxe Double Quarter Pounder (I was hungover), coming to £14.66. Turned up with everything except the actual burger. Rang Uber Eats and they processed my refund, which was a £2.91 flat fee. I rang back but that was their (obviously scripted) response, flat fee, so nothing close to the item that I didn't receive.
Walked past the restaurant in question a few hours later and nipped in, manager refunded me there and then.
Shut Uber down, abysmal company.
