Who called from 6503811432

Call frequently, never leaves message. When I answer they are trying to off some type of home remodeling.

Called and left no message 4 times between 7/18/17 and today.  Sometimes it takes me a while to learn.  Blocked.

aaug 8 2017  910am  ongoing cold contractors calls  frequently will be open line then hang up

Another unsolicited call at 9:28am PDT with caller id of "UNKNOWN NAME" and they did not respond when I answered.  Out of curiosity I called the number back and apparently it is spoofed (as it is no longer in operation).
