They took an unlawful charge at collection ('fuel deposit') which wasn't in any of the communication or paper work on booking. They refused to allow the rental unless £95 was debited from my card (which was much more than the entire cost of the booking). The car was dirty, and the petrol tank was only three quarters full. On return I had to bring the car back with a full tank so paid out an additional £25 on fuel that they won't refund. They also are not refunding the £1500 deposit despite the car being returned and it being cleared for return. This outfit (I used the Heathrow branch) should be avoided at all costs.
