Yeah, I've had my résumé cloned a number of times.
Sometimes they take the whole thing and paste in a different phone number (with country code) or email address, as they did with you.
Sometimes they just steal your content and feather that into their own résumé.
If you want to have your résumé "out there" to win and influence clients, there's not much you can do about these kleptoparasites. You could lock your PDF, but that will only slow the KPs down a little bit and will inconvenience your potential clients who want to feed your data directly from your PDF into their database.
Often, someone who receives the cloned résumé will already know you independently, and will alert you. That's usually how I find out.
You could craft a nasty cease & desist letter, and send that to their email address.
If you can determine whether the miscreant is a member of any professional organization, you can alert that organization to their misdeeds.
Otherwise, this imitation game is a fact of life.
