I do think you supported from that card. Normally, I would think you'd be SOL, but I would wait until 2/2 and see if you get this $400 credit. You can have it ACH to your bank account or transferred to another acct if you have another Chase balance.
I'm not sure when you canceled the card, I'm assuming sometime in January since you received a Jan 26 statement. If nothing materializes by 2/2, you could see about reopening the Chase card, which sounds like Chase will do if it's a card closed within 30 days, but I don't have any personal experience with that. IDK if that would help these 40k points materialize, as usually when you close an account that has points, you lose the points (not sure if that's immediate).
Is there a date on the 40k redemption? Does it match up with anything, like perhaps the date you cancelled?
