I just received a call from this number as I was doing my weekly "who is calling now", it is a National Survey, but I think they may be legit because after introduction he asked if I was 18 or older, I said no, he asked if there was someone home 18 or older, I said no, then asked if they would be home before 9PM I said no, so either he was legit or someone is gonna drop by and try to rob me before 9PM
