So I got my new cc, and did what I needed to activate it, etc. In the meantime, while looking at my activity online, i didn't see the one charge that was mine. So I called, to make sure they hadn't lumped that in with those that I didn't make. Turns out, its still pending, but they don't have it listed as one being disputed. Ok fine, great.
The rep also told me, even after my card was cancelled, someone kept trying to use it! multiple times, and it was declined each time. Weird. I also said I'm trying to figure out just how someone got my number, info, etc. since I really don't use it much, not nearly as much as my Am Ex. He also told me they are looking into that as well.
