There is a robo-calling group that has a fetish for numbers in the 703-382-64xx range. They call daily, switching the last two digits frequently. All of the calls are spoofed numbers, robo-called on a tie-line. Caller Id says Springfield VA, but the call center is probably in hell. Blocked!
Beatrice has the accurate assessment. All of the numbers in the (703) 382-64XX group are spoofed, as you can program any Id and number into a robo-caller. Maybe the Devils behind this endless harassment calling are stupid enough to think they can fool us by this daily switching of the last two digits. Blocked.
