Who called from 7347994215

I just received a text from this number, when I asked who it was they replied "Lol if you wanna know who this is add me on yahoo msnger, my name is txtgirly71".  I'm not playing this game, all of my phone numbers are on the DO NOT CALL lists.  Guess I go report them there too.

I got a text from this number which say's "hey Andrew...."

I to just received a text from this number identifying me by my name. I do NOT know who this is

I got the first text saying hi with my name, and then when I asked who it was, I got the same reply as Tresa.

I received a text with "Hola Mandi??" to which I replied "??" and then received "haha if you want to know who this is you to add me on Y! msger, my id is txtieflirt83"  I keep getting random texts with my name from numbers I don't know and when I look them up I see similar complaints as these...what's the deal?  Can anyone help me figure it out?
