Somebody put my cell phone number on their Facebook profile page?

[kochinae-chan]

Lately, I've had random numbers texting me asking for someone named "Richard". I got one random texter to tell me that this Richard guy has my cell number as his cell number on his Facebook profile. I have no idea who he is, what his last name is, or how to track his Facebook down so I can ask him to fix it!!! I'm really fed up with the stupid texts and I don't know what to do!! Does anybody have any ideas?? ): should I email facebook and ask them to try and fix it?? Any ideas are appreciated!!! :/
Also, when I asked the random texter for his last name, they stopped texting back. They're smart, I guess. So I have no chances of getting his last name. :/
