We booked through rentalcars.com for a recent trip to California. Upon landing, we were told by the rental car company that they did not have a car for us. We immediately called rentalcars.com who told us to reserve a car with another company and they would reimburse us for the difference. Upset and tired from traveling, we had no other choice. We paid an additional $300 out of pocket to have a car for the week. Once we returned home, I sent in our receipt as we were instructed to do. We received an email from Natasha in Customer Service on July 19 to which we immediately replied. It is now August 4 and we have had ZERO communication from rentalcars.com. I have emailed them several times with NO response - not even an update on the status of our claim. Don't be fooled by the low prices, as the saying goes, you get what you pay for! I assume we will be out the $300 because of their mistake. Shame on us for trusting that they would take care of us. Never using rentalcars.com again. Oh, and we racked up $120 in international phone call charges since they are based in the UK. So really I am out $400 because we chose to book through them - never again!
