Who the hell is this, emailing me at 11:26?

Oh yeah, yesterday morning I received the following text from a number I didn't recognize. "U told billy u told dss to stop the checks thats bullshit." I texted the person back telling them they must have the wrong number. Since that moment, I've become very concerned and I am considering checking up on the person who texted me and inquiring as to whether or not it was in fact, Billy, who was responsible for the checks stopping. Because if he is.... that's bullshit.
