When I bought this offer at Kayak it was after the credit card purchase where a special message appears saying extra fees may apply. Well you should better say your price will get increase over 500% due to extra fees. I ask for small economy car that's it. First catch, I was charge with full tank service. I thought ok it's nice. But when I returned the car they charge me for another managing fee. I paid over 120 full tank and when I returned the car with tank in 6/8 they refund only 30 euros. Most expensive gass ever! Then I paid for full insurance and because the car.was fully covered they.just don't care.about the car and gave me a car with bumps everywhere. Finally they took 300 euros from my credit card as deposit. In summary they own me 350 euros that I haven't received yet one week after service.
