Booked rental car through Rentalcars For December to Jan 2020 and was given a booking voucher to use a Europcars at Tenerife south airport Europcars said they had no booking from rentalcars so had to book another with Europcars which was both more expensive and a downgrade plus additional charges for full CDW . Now fighting with Rentalcars for a refund as they are saying the charges from Europcars are for additional CDW which are £350 !!! and more than the original charge for the car and CDW insurance from Rentalcars together. Rentalcars cannot be contacted directly in the UK by phone or by email ...they have to contact you after leaving a message Complete scam artists and not to be trusted
