Once is likely a mistake, IMO. However, if a hotel employee, particularly someone in management, is repeatedly reinstating a cancelled reservation, that sounds like consumer fraud to me. In Massachusetts it would be classified as an "unfair or deceptive trade practice" which would entitle you to up to triple damages plus attorney fees. I'm not suggesting that litigation is the way to solve this. However, if they eventually charge your credit card for the night(s), I might use this as a negotiating tactic to extract compensation points from the hotel. While FT regulars know that I often side with management on some of the complaints we see on FT, there is absolutely no excuse for this type of behavior.
