Received a call from this number 202 753 7620, did not recognize the area code so did not answer this was a few days ago looked up on line where this area code was from and discovered other people had the same bogus call.......
Called my DNC cell, I did not answer because of the area code. Thanks to Alex and the rest of you who posted on here. I added to my address book as SPAM and only wish I could set up these calls as no ring.
