I agree with Magic. There are some people who just dont want to cooperate. We have had some of the same problems here but we have buckled down and sent out some serious letters giving options to comply or suffer closure of the account. If it is any kind of high risk, and it sounds like it is, I would ask myself if the considerable amount of funds in the account are going to cover the penalties that might be assessed in the future. If he his that kind of customer who threatens, then let him walk. Just thinking of the hassle of CIP issues alone
would want to make me stay where I am and comply. If you want to PM me, I will be happy to share my MSB info with you.
