CarTrawler — cartrawler rental for dollar is a rip off

This company is no good... I rented a mini van for my vacation... Paid over $100 extra for mini van... When I got to airport dollar rent a car told me they had no mini vans and gave me a car. Cartawler will not refund the correct amount between car vs mini van. They told me dollar rent a car will not issue the correct amount. So according to cartawler it is dollar that is the rip-off t please do not use this company or dollar... You have been warned...
