The Amex supervisor called me yesterday and said that their Delta liaison could not do a thing. Delta would not talk to him due to privacy issues. I don't know why they would not call me. I originally thought that the liaison was an employee of Delta but he works for Amex.
Amex has traced that they have given the miles (and a guess the mqms) to Delta and now it is up to them to put the mqms in my acct. Over a month and dozens of calls wasted.

I will be calling delta some time today.
