I hired a car from Budget Northern Ireland International Airport. It was all paid for, all I had to do was pick up the keys. A £100 Fuel deposit was briefly explained to me and I signed the 5 page document and left. A day after my return I realised the £100 deposit never went out. Instead a £201 protection cost that I never needed and which was never explained to me at the time. I'm now over £200 down and their explanation is "well you did sign it." Beware… total scam
