They called on my cellphone number,which is a violation of the federal registry. Only a select few of my friends have that number, they left no message... probility very high it's a scammer is very high.
Typical robo-dial/scammer call pattern - land line rings, caller ID shows "Washington, NJ" (there are six Washington Townships in NJ, and none are in this area code), do not recognize, did not answer, no message left = SCAMMER = BLOCKED ! ! !
