Rentalcars.com are making promises that they don't keep. They offered a free second driver. Thrifty Lamezia did not know anything about this offer and demanded more than 10 Euros per day. When contacted, rentalcars.com wrote (after four days!) that they were only the brokers and could not do anything about it. They said I should contact Thrifty (in the meantimes 500 km away), pay the second driver and then claim a refund by using their claim forms. Instead of doing their job they expected me to make phone calls in Italian, contact the rental company and fill in forms. There was no support whatsoever! Rentalcars.com let their customers down!
