Who called from 2627576546

Just received a text msg from this
Number don't know who this person
262 757 6546

Got a text message from this number.  They already knew my first name and when I asked who it was got a message about adding harpergirlie on my IM.  Odd that they knew my name since I don't give out my cell number for much of anything and don't use instant messaging.

I was told to add kaylachickie6 on y! IM

I also received a text say" Hey (my first name)."  then "Ad my ID on y! msngr...id is kaitlynchick9".  When I asked who this was.  I got "Sry I have no battery life. :(".  I also do not know how they got my number or first name.  I also do not use instant messaging.  Beware.

Said Hii to me and i told them who is this and no answer for the past 3 weeks, stalker...
