Terrible experience - scammers

Overall bad experience. The company has a very predatorial approach to customers attracting them with a hot deal which in the end turns out to be way more expensive in the end. I booked with a supposedly great deal together with a flight reservation and the offer was 35euro for the rental. The final price we paid was 219euro... In the contract which is only available in spanish they wrote that I gave consent to a pre-paid fuel options which costs extra 30euro (so I can return the car without refilling), but I never agreed or was asked about it. The presonnel was trying to force me and other customers getting a bigger car for "only" 20euro per day more, as the one I rented (renault clio) is "not good enough for the hilly roads of the island". 90% of the cars in the island is renault clio or sth of the same class. BTW. I booked ford fiesta and got clio instead... Avoid this company, avoid fuel pre-paid option, they will always cheat you with it. My experience with small, local rental firms was much better.
