Keeps calling and as soon as I answer, it hangs up
Obviously some kind of marketing or scam caller

Caller: Wine company rang at random

Boy! I regret answering this call. Aggressive in ya face wine salesman gave me a serve when I politely declined his offer of "quality wine". I've now blocked this number.

Twice now I answered and no one spoke. I got the feeling someone was checking to see if my phone was being attended. I see from other posts a pattern is developing.

Calls but doesn't leave voice mail. When answered hangs up. Bloody annoying! If you're going to try and scam someone you might as well say something!
