I had a problem with no available cars. Booking Group did not change my reservation over so I had to make a 2nd booking to get a car. When I filed for a refund on 1st booking in writing and by phone they told me 5-30 days for answer. At 30 days after several phone calls they refused my refund. I called 3 times from 3 different phone numbers and hung up on all 3 times after being on hold 30 mins each time. They are scammers and LIARS.
