You don't really lose points from closing a CC unless it either significantly effects your utilization or you only have a 1 or 2 revolving accounts. Do either of these apply to you?
I recommend calling the CCC and asking them to waive the AF based your long history with the CCC. If they refuse after several attempts with different CSRs you might want to close it, but before you choose to do so you might want to consider the instances above regarding effecting your score.
