I can now see your problem but don't have a solution. Perhaps you could phone BA to waitlist yourself and request that they e-mail or fax you conformation. Have you tried asking to see a security supervisor and being escorted to the ticket counter? Perhaps you could contact the crew when they arrive at the airport and ask them to give a message to the BA ground staff? Is there a town office that you can visit to get a date put on your ticket? Sorry that I can't be of any more help.
