I paid twice for a rental car rental in UK at Liverpool airport. Had to book Green motion because no other companies on offer on Rental Cars site. I paid €369 on Rentalcars online and chose not to take extra insurance. On collecting the car I handed over my Visa gold débit card for the deposit and was told they needed a credit card. I don't possess one. Initially it was £50 per day extra then they reduced it to £45, so £450 extra. Either I paid it or didn't get the car. No other REPUTABLE car rental company is as high handed. I resent paying over £800 for a rental car. Totally inacceptable. I will never hire with Green motion again. Avoid at all costs if you don't want to be ripped off.
