Pretty sure this was a robocall. When I answered the phone, they asked for a name I didn't recognize. I asked " who are you looking for?" Then there was silence, and then they repeated who they were looking for in same tone as before. I asked one more time for them to clarify. Silence again, then they repeated again, so I hung up and blocked number.
