Got a call from this number. The caller did not leave any message.

a call on my cell phone - didn't leave a message.. I don't give out my cell number... not sure who they are

I just got a call early this morning and the woman was rude and called me a liar when I said I wasn't the person she was looking for.  I called the company back - it's NARS, a debt collection company and asked that my number be removed from their database.
