They sometimes pull a trick of sending a check for a small amount, and then when you deposit it seize the account. This looks a little high for this trick, but you might want to open a small account at another bank or S&L and deposit it there and wait a while and see what happens.
I can't imagine why they would want to sieze our account. I haven't done anything wrong, illegal or suspicious.
Except maybe being registered as a Republican in a solid Democrap city.
