I had the same problem with no luck
Me too. Best I could get them to do after a ton of phone calls was offer me 3k SPG points.
One thing I noticed every time I called is they first would ask me for the promo code. Being that I applied through a link from this site I didn't have a code, but eventually I was able to figure out what the code was on my wife's app. Maybe next time they ask I'll just give them that code, but I doubt it'll work.
Only thing I can think of is something going wrong with the cache, but I'm pretty sure I remember applying for the cards on separate computers. One way or another, I take screen shots of every app now.
