My USBank acct was shutdown. This was due to some cash deposit activity on banking side. I was depositing 3-4k per months (from US Bank Visa buxx cards) and got a call from a banker asking source (in late Oct). I told him the source details and he sounded confused.
Sensing trouble I emptied the account and closed it very next day. Low and behold, got a letter from US Bank (mid dec) that my carlson CC was closed (had only 500 points as I emptied close all points after the third free night benefit was dropped in '15).
No reason was provided and I did not bother to call either. Credit report shows card closed on my request. I wasn't impacted much as I had only one CC with them that I would have closed anyways (one the AF hits)
