A scam spam group, operating a robo-caller on a tie-line, is fixated on numbers in the 703-382-64xx sequence. As we were away on family vacation, we came home to find that these people called multiple times daily, changing the last two digits every few hours. Are they trying to fool someone? Added to the call blocker. Caller Id says "Springfield VA."

I received 6 calls from this number today; 1st and 2nd at 0943 (within minutes); 3rd and 4th at 1335 (within minutes and the last two digits changed from 33 to 30; 5th call at 1343 from 33; last at 1633 from 6410.  What a waste of time and effort on their part.  I don't answer calls from numbers I don't know - PERIOD!!  This doesn't include a crap load (21 total) received today.  And people wonder why I don't answer my phone anymore.

These are calls from mortgage loan offices; most from Quicken Loans. If you recently clicked on a re-fi link or   Obama's HARP link...... they have you !!!!! Even if you answer and ask to be taken off the call list, they have a robo call for over 100 numbers. The calls will last for several weeks
