Mrs User Name applied using the 25K link 5 days ago.
Card arrived today, activated and immediately messaged MR - Points balance saying that she'd applied using the wrong web link in error and had intended to use the flyer with the code 5894.
Reply received within a couple of hours - the 25K will take 6 to 8 weeks but if she messages back once the $500 is spent then they'll apply the 50K there and then.
Result.
