rude crude cursing teen girl who has her number and her foul txt messages on my kid's cell.  Unlisted land line.  I called number unblocked to ask who this was, and I was greeted with a foul mouth child who said she didn't know me.  click.  then a minute later, my home phone rings and i am alerted to a text message my land line rec'd-who knew you could do this?  Anyway--more swears.  I told her I was a registerd PI and I would find out who she was.  Then her mom calls, no ID given.  I told her to check her kids cell and same- i will look this number up at work.  No further contact was received.  Who is this little foul mouth child who is harrassing my kid via cell txt?
