I was Gold status GP. I went into the Hyatt web site that said, "permanent Diamond Status as long as you have the card." It was very early on the morning of the "mistake." I applied and was instantly approved. The card is in the mail. Has not yet arrived.
I am still Gold status on the Hyatt website. Chase website says I am Platinum.
What should I do to get the Diamond status I was promised by the Hyatt website?
