Who called from 9178184792

Same.

No one on the other end. Just dead silence.

A few hours ago. I called back,and it's a survey to check how we'll be voting

Left no message. Caller ID New York NY.

I picked up with the intention of screwing with another unknown scammer. 5 seconds and no answer. Just as I hung up I hear hello, but it was too late.
If this was a political call to find out who we planned on voting for I would tell this unknown caller that one of our rights as voters is called a secret ballot and it's no ones business who we plan on or eventually will choose to vote for.
