Logged into my F9 account and saw that it said my points were expiring in 10 days and panicked a little. That didn't seem right since it didn't feel like it was that long ago that I had my last activity, and I was correct. Last activity was less than two months ago (transferred miles from another account into mine.) Shown date doesn't match 6 months from any other activity I've had. Where they got the expiration date, who knows. If my miles actually expire on that random inaccurate date I'll be awfully annoyed.
So this isn't quite the same situation as most others, but the title matches. And now I have to waste time trying to figure it out. Not sure why they don't think a functional website is an important part of their business.
