I have a feeling this is a new bank of "say yes" scammers.  703-382-6410 thru 6441 ... so far.

703-382-64XX - I keep blocking these buggers. See in the logs that they call 6-7 times a day.

These retards are fixated on using every possible number in the 703-382-64XX group, calling multiple times daily, and reprogramming the number in their robo-caller hourly. Caller Id says Springfield VA. Typical number issued through the Verizon office in Washington VA, used almost exclusively for telemarketing frauds and related telephone terrorism. Blocked. Our call blocker now has over 500 blocked numbers, with new ones added daily.

Scammers calling several times a day from this number and others in the 703-382-62XX range. What a strange way to get money from people!

Multiple calls daily from 703-382-6411, 6416, 6417, and 6441 so far.  Blocking each and every one, as they occur!!!
