Who called from 4077770350

the phone rang no one on the  line. the number came up unavailible

No one on line!

A spoofed number-In my book,its a scammer.

I do not answer when I do not recognize the phone number, but was curious to see if they had called anyone else.

I "accidentally" answered but no one was on the other end of the line.  Call came as "Name Unavailable".  Just another annoyance to add to my blocked call list....
