Just tried for 2 cards opened in 9/15 (business and personal). No dice on either. Oh well...
Maybe huca on another day?
I've heard that bonuses they can offer you change daily, so HUCA is most effective on different days.
Also, make sure you call during us business hours, you usually talk to an American.
If it helps, I called the Platinum number 1st, and she transfered me over to the SPG number. Maybe try that...
