I am living a very similar experience as the OP unfortunately. A few months ago I was booking tix with Southwest Air and they had the promo of a $200 statement credit. So I was like cool- my $800 plane tix will only be $600. I would not have opened a credit card if there hadn’t been this promo and that’s why I’m so pissed. Before I apply I read all the terms and see that I meet all the qualifications for the credit. So I apply and get it, find that I can’t book the tix until I get my physical card. I called Chase to see if I could get the info to book it that day but no. I wait a week, get it, and go to book my tix and see the promo is still on the page and I’m like awesome. Buy the tickets and wait the 6-8 weeks to see the credit. Never see one. Now I’ve been going back and forth with Chase supervisor being told that that card isn’t eligible for the promo even though I have a screen shot of it on the Southwest page when I was booking. I don’t know what to do. I feel like they’re false advertising and I just want the $200. 😞
