I booked a night at Flagstaff SHS 27th Feb for 1 night at Marriott.com and I found a lower rate at otel.com and dhr.com. So I submitted a LNF claim but somehow Marriott claims that the hotel is not available on the dates that I stated. After I got the denial of claim I searched again and the price was there

So I submitted another LNF and still got denied. Anyone knows what happened?

Thanks for the help.
