Complaint Review: Expedia

Through Expedia.com I rented a car from Dollar A Day Car Rental which went through a search service called "Cartrawler" and a UK billing service that billed my credit card $164 USD for a one week econimy car rental.  I received a smaller and different car booked, and Dollar A Day would not rent me the car unless we paid an additional $165.00 for "Cailfornia Liability Insurance" after my 15 hour flight with two kids in tow. My voucher did not mention this extra fee, and I assumed I would present my voucher and obtain the car. Because I signed this tiny computer screen just to get out of there, I thought I could resolve through Carhire and/or credit card company. If you have to sign anything...just sign "declined" instrad of your name and the agent may not notice.  This is a scam and I would advise not to use Expedia, Cartrawler, Carhire, and especially avoid Dollar A Day Car Rental because they will quote you a low price and hit you with a fortune. If you get this scam, contact the manager of the location, hold your place in line and do not allow others to get their cars and make it as embarrasing for the agents as possible.
