I was looking for a hotel in Keystone, CO for my husband and I for Presidents' Day weekend (18-21 Feb, 2011) and found a hotel we thought we'd like on several sites. Priceline had it cheaper (without bidding), but as we had had success with Hotels.com before, I decided to call them to see if they would match the price (per their website guarantee). The representative verified the price I had found on Priceline (over $131.00 less) and said they would match it. My clue that this was not going to go well, came next, and I should have run... she said they were going to charge the original amount and then a credit would be run, within 2 hours, to get to the adjusted amount (as she could not do it). Well, 8 days later, still no credit. This is after 3 phone calls and as many emails. I've now gotten my credit card company involved, particularly after the last call to Hotels.com 24-hour customer service line. I got a frontline representative, so was very quick to say that as I had been at this for a week, I needed to talk with a supervisor. She left the phone for several minutes and then came back and said none were available. I asked if that meant none were there, her comment, "No, helping other customers." She did not/would not give me the option to hold. DO NOT USE hotels.com (and as they are affiliated with EXPEDIA, I'd say not use them either).
