I am having an extremely difficult time getting my referrals to post as well, though with my Platinum Amex. I got nowhere over the phone or via secure message, so I am writing in and sending all the documentation of the names/dates of referrals and the email confirmations that Amex sends back when you make a referral. I'm not sure if that will work or not, but it is the next logical thing to try. I'm not sure how having the closed account will come into play for you. I imagine it will make things more difficult, but I very much understand your frustration with the referral issue.
