Unathorized charge a couple days ago on my Hyatt CC from a Hyatt in California where I've stayed before, but not for two months. Called the property and got the runaround for a couple hours until I called the Diamond line, who promptly got someone on the phone. (As an aside, I've found that any silence or intransigency on the part of an individual property is very quickly rectified by going to the corporate Diamond line).
Nobody at the property seemed to have any freakin' clue why there was a $400+ charge on my card from a property I checked out of 2 months ago. My only recourse was to file a fraud alert with Chase and get a new Hyatt card.
I'm guessing more fallout from the data breach, maybe?
