The OP needs to call MP and cut out the middle man who apparently doesn't know what is going on with this past itin.
I've said it many times ---I DON'T SEND THIS NEW AIRLINE E-MAILS OR LETTERS! IF YOU WANT SOMETHING REALLY SCREWED UP AND WANT TO BE SUPER PISSED, CONTACT CUSTOMER SERVICE WITH AN E-MAIL!
OP, give MP a call, if you want this thing handled correctly, and disregard the response you received!!!
