I am looking for feedback or suggestions.

I signed up for the Memphis triple miles promotion. I also booked my flight online. It was my first booking @ NWA.com.

My FF acct was credited with 4000 for the 1st time purchase @ NWA.COM but not the 7200 miles for the triple miles. I also was not offered a choice as to which of the 2 (assuming I can only get 1) promotions I wanted. Although NWA has been terribly slow responding, I have exchanged several emails. While I have not received a response to my last email to them two weeks ago, they have essentially said via email that I am only eligible for 1 promotion and that I have received it.
