Add one more voice to the chorus of yeses.
I know of at least two cases where a “no” ended up with a B”H happily married couple.
Since the girl was the one who said no, I strongly agree with “NY Mom” who said a third-party shadchan should be used – it could be very uncomfortable and even seem stalker-ish to call a girl directly after she said “no”.
