I have been receiving calls form this number for weeks now and I never pick up or call back and I am on the no-call list.  I use a cheap phone not a smart phone for privacy reasons.  If I que my phone for reset after expunging this number from my received calls list, I am not menaced by this trash call for several days.  I suggest that the number plays like a commercial marketing firm, when in fact it is just another US Security snoop for junk phones.  Runs a tracer on your phone real time.
