Then why did your title say 'credit card fraud'? Where does the credit card come into the story?

I said "potential credit card fraud". Sorry for the confusion. The potential fraud is not being done to me. I just wanted to know what I should do if I suspected it.

OK, that makes more sense. I guess it's hard to fully explain a situation in an Ask HN post.
