Welcome to the forums guardmom,
Don’t worry about it, I have deleted your other post so no harm done 
Congratulations on your card! I guess they’re a little busier now at Capital One (maybe it’s all those good reviews they’ve been getting on this site, lol). If they told you it’ll take 2-3 weeks then it’l probably be that long, but it could be less than that I suppose.
Are you trying to rebuild or establish credit? Please don’t forget to come back and report your progress with the card. We are not credit experts but do learn a lot from each other’s input
