Calls and hangs up

I called number back 'Shawn calling for Nationwide, Progressive and State Farm trying to get your auto insurance around $50' I hung up

I answered  the call and a guy named Ted said hello, this is Ted can I help you?  He acted like I called him, then pretended he could not hear me, kept saying hello...I hung up the phone!

called some kind of recording I think it said "Frank" then they hung up SPAM

They called me and when I picked up they said "blank..." when I said hello again they hung up
