I made a reservation for a stay 3 weeks in advance in Chicago at the River Hotel through Hotels.com 15 minutes later I found out that I had to depart Chicago a day earlier, so I asked Hotels.com to reduce my reservation by that last night. Hotels.com would not make that change without me paying a penalty equivalent to the full 4 night stay. Alvin was the supervisor that I ended up hearing "no" from, so I asked him one last time if his final word was he wouldn't do a damn thing to help me. Then I got a warning against using profanity. Never EVER again will I even consider using Hotels.com
