Who called from 9185520123

This number has called me twice in the past two days.
I'm assuming it isn't important since they didn't leave an actual voicemail.

I answered, said "Hello" twice, no response, just dead air.

Same here

Called no message. My number is brand new.

may be a computer scam where they say that ur computer is infected and of course they will fix it for a charge tell them to go f there self
