Call about a vehicle we haven't had for over 2 years have talked to 3 people this week they hang up when you tell them you haven't had truck. This is ridiculous

Caller keeps calling and hanging up

Calls and hangs up. Blocked number.

No on the other end of line. Called back and advised if I didn't  want this number to call again  to hit #1. I did.

This # just called my cellphone.  I answered on last ring...silence.  Said "hello" again, then heard a robo sounding woman say "goodbye".  Won't answer this one by mistake again.  Weird.
