I have had 2 BW credit cards (not at the same time) and with this 60k promotion I applied on behalf of my husband who has a good credit rating and never having had the card before. We got the same "wait and see" message and a week later got a letter saying he was rejected.
He called and was told I had (mistakenly!) reported his personal income at 700k instead of 70k!!! Yikes, that must have raised a red flag. After some time on the phone he agreed to send in proof of $70k income and we hope he will get the card and the points.
I plan to apply again before the promotion ends in August (I cancelled previous card in June) and will be more careful....
