Not helpful at all

My flight was delayed by 5 hours because of the drones at Gatwick. When I got to the rental place they had given my car away as they thought I was a NO SHOW. They must have known the airport had been closed and the flights were delayed. They would not honour my booking and said that they could give me another car but i would have to pay more. I had travelled from Australia that day because my father was unwell and had to get to Essex asap. I felt under pressure and paid additional monies to get on my way. The staff were most unhelpful and i wasnt the only one who thought this. There were a few of us waiting for cars to pick up at the same time whose flights had been delayed. Will not be using them again. Total rip off. BEWARE.
