Got hit with FR after spending about $3K on SPG points on the last day of the 35% bonus, missed their call (thought it was spam).
I placed my income about half way between my household total income, so I'm planning to win on this end if they were worried I couldn't pay off the amounts. This was quite embarrassing as I'm traveling and all of a sudden can't use my cards (like SPG Biz).
Definitely will leverage this to get credit limit increases / threat of CFPB.
