Interesting. Tried to get the Diamond status based on being Platinum for last 5 years and my pattern showing that I would make Diamond in the next 4 months.
I received a form e-mail asking me to send proof of top level in Starwood or equiv.
I have now taken my business elsewhere . Shame , as the A/P Hyatts are quite good, but - guess what- the InterCon is about a third cheaper in Sing and twice as friendly!
