Ordered a burger and fries from Five Guys but only received the burger. Complained to Just Eat and they eventually refunded me for the missing fries but didn't refund any of the service fee I paid, which was a percentage of the order total (including the fries). So I had my meal ruined but was only partially refunded and received no actual compensation. When I complained further, they insisted this was company policy. Wow.

Placed order 11:30pm, order wouldn't validate so had to raise a support ticket. They validated my order about 6:30am the next morning. Frustrating but I've had no other issues with ordering from them.
