Who called from 3304003423

Got the message from previous post which I responded to, with 'who is this' then about 10 minutes after original message I got this:

just got the same text from same number. Odd thing is, the gamer name was someone I know but don't associate with.  I googled the gamer name to see who it was.  That was weird unless they gave my number out which would then be downright psychotic.

Got a text from this number: How come you aren't playing Dice With Buddies on your phone with me yett?? http://bit.ly/H5Lk94"

who is the smart guy texting my phone when I dont give out my number and how in the hell did they get it? This is the first spam text i have ever gotten and I have had this number for 10 years

I just got the same message. Thanks to this board I immediately typed in STOP! How did they get our numbers in the question?!!?
