Has anyone here had experience with this happening either unintentional or on purpose:
1. Spend 15k, get FNC in HH account (since they cannot be revoked)
2. Something gets refunded, so you go below 15k, and the online tracker shows such
3. Spend again to hit 15k "again", ...
What happens? Did you get another FNC? I'm guessing not since that'd become an infinite FNC glitch and get shut down rq. I just want to know so I can leave my 14.6k/15k alone (after a refund) instead of putting in $400 again. Amex won't really hold this against you somehow, right?
