Fair deal - what rate did you pay (upgrading on points usually requires a minimum rate)? However, this shouldn't have happened to begin with as you were confirmed. My coworker had a horrible experience last year where they screwed up the diamond upgrade and instead booked 2 rooms (regular room and suite) with the suite at their CNY5000 rack rate! They were very firm and unaccommadating. A quick call to the US Hyatt desk and they were out the door towards the Park Hyatt with the front desk manager wondering what happened when both reservations got cancelled and refunded.
