I made a 7-day car rental via Hotwire. When my plan changed, I called them immediately - before ever picking up the car - and canceled the reservation. The staff on the phone confirmed that it was canceled. I never picked up the car. Then, when my credit card monthly statement came in the mail, I noticed the full charge of $238.67 - for what? I called them again, but the staff denies that the reservation was canceled, because the rate I was quoted was a "special rate," which had locked in my reservation. That's not what the staff had told me the first time when I called to cancel. Hotwire knows what it's doing. They have developed a methodical scam, using cunning practices, to scam customers. I will NEVER use Hotwire again, but the company needs to be sued and voted out of existence. It's a matter of time that this will happen.
