received a call from this number and they hung up when I answered. called back and received a recorded message that said my number has been hijacked if you received a call from this number call the fcc.

Two calls from this number, no message.

I have gotten several calls from this number over the past few days.   Sometimes is says "unknown"  and sometimes it says "Elliot P. Guerny."      I googled Elliot Guerny and it comes up that he lives at 25040 SW 121st Pl
Homestead, FL 33032-5985.    I don't know anyone in Homestead Florida.   (Google Earth shows that address to be a house in a subdivision.).      I don't answer calls that come up as unknown and this person never leaves a message, so it must be a telemarketer.

Scammers are tricky and can manipulate what is shown on caller i.d.  I received a call one day that showed my name and my telephone number on the caller i.d. unit.  I just hope they didn't call a bunch of people with my info showing up.
