We booked through rentalcars.com and rate included CDW. When we collected car a Barcelona Gold Cars said we had to pay additional insurance. We argued that our confirmation showed it as included but they said internet booking companies lie about costs and would not release car. We contacted rentalcars.com straight away to complain but as we had already signed the contract there was nothing they could do. Apparently you need to tell Gold Cars to put it in writing, obviously the internet booking companies are aware of the scam.
