I have booked a car for pickup on [protected] using Ryanair.Com. Booking number is GB594709470. I was charged CHF 53.94 by Ryanair on 20th May. When I went for collecting the car on 22nd May, the rental car model I have choosed FIAT 500 was not available. Booking agent has told me that the car doesn't have fuel in it. He offered me a free upgrade to a Honda Jazz. I took it reluctantly as I prefer a small car for ease of driving and parking purposes. Today I have checked my credit card statement. GreenMotion has charged extra GBP 79.80 to my credit card account on 24th of May for no reason. I would like a full refund of the same.
