I queried whether I could be ‘invited’ for the offer, and received the following:

”I understand that you are interested in the 'Straight to Diamond' Offer. We have unpublished marketing criteria for targeted offers and promotions based on the system's strategic approach. Based on performance activities, demographic location, record ratings, point earnings, tenure, and many more. Also, it includes limited invitations and a selective business approach. All are bounded by specific program terms and conditions. I hope I was able to answer your inquiry.”

Now that is some excellent customer service waffle!
