I made reservation online for my trip to Las Vegas in July 2008; however, I was not authorized Reservation Rewards to charge to my credit card for $12 monthly membership fee.

I had cancellation confirmation by email, but I continued to get charged for another month in September. I have not received October bill yet. I rarely travel and it is unfair to charge for the service I don't need. read full review »
