Who called from 3602277536

Called my cell, left no message.

Called me DNA, no msg. I called back using a spoof app. Got 1/2 of a ring, then dead air

Dead air, nobody responded when I answered.  I hung up.

Calls constantly, DNA, no message left.  Caller ID shows Core Home.  Have no clue what it may be.  Apparently being on the National Do Not Call list means nothing!

Waited approx 20 seconds and the automatic computer generated voice asked me if I wanted to Market my home in my area.
