Hi, I am from Australia. I rented a car from Dollar Rental A Car in Las Vegas, then dropped it off in Phoenix about 19 days later. When I picked up the car in Las Vegas, the staff working in Las Vegas office asked me to pay about $450 in cash for the car. Then after I returned to Australia, I found out Dollar Car Rental charged me again. Later I found out that it was actually the staff working in Las Vegas office took my cash payment illegally. However, because I lost the initial receipt after I paid the cash, neither my credit card company nor Dollar Car Rental is willing to do anything. I asked Dollar Car Rental company to check the video, but the reply from their customer service is to ask me to report to police. I wonder if anything has similar experience and know what I can do for this kind of scam?
