Stayed at the Grand Hyatt Melbourne in early September. Received a phone call from them a few hours ago mentioning they forgot to take out the points for my points stay. (24,000) (After thinking about what happened I think I figured out why they never charged me/loop hole in their system)

They mentioned that they needed to take the points from a future points stay in 2012 I booked (Park Hyatt Beijing). Couldn't finish the call and told them to call me back tomorrow to sort it out.

Called Plat line and the rep says he has never heard of a hotel canceling a hotel stay to redeem their points they are owed but he has heard of accounts going deficit.

Has anyone had either thing happen to their accounts?

I know I've said this before in SPG sub-forum for other reasons but I think I would stop staying at Hyatt if my account was -24,000.
