I had two stays that did not post. I faxed in two letters and nobody responded. I then wrote a regular letter and mailed it. Nothing. The two stays were important to me since I was just under Platinum status. I checked into a Hotel in January and presto No Platinum gift. I later received a Survey in the mail. I cited that I expected to be Platinum and would no longer be staying at Marriott. I'm a meeting planner and reminded them I spent 75K with Marriott last year alone. Wow! Got a call from a special rep and she gave me 10,000 points and Platinum status. Marriott still loses since in the meantime, I shifted my meeting to Starwood. Kind of late for Marriott. Got my points, but I'm now splitting the business between the two chains. What upsets me about Marriott is that they don't respond to your correspondence until the customer is really upset. Pretty bad service if you ask me.
