I ordered a car through rentalcars, when I came to pick up the car, the representative who received me started the conversation by saying that it was a shame that I ordered the car through an external company, that in the future I always have to order through the rental company directly.
He threatened me, that if I take the vehicle as I ordered through rentalcars, he will have to block 2000 euros on my credit account and it will take them several months to release.
He forced me to take full insurance through the rental company and said that rentalcars collection would be cancelled.
But i was charged twice. Very bad service. Stay away!
