Phonetiquette

pet-pieve: I answer the tele­phone, (though it reads “unkown caller”), the voice on the oth­er end asks for some­one who does not reside here, and when I polite­ly inform them of this fact, they hang up with­out response.

And, they call back twice, with the same bad man­ners.

…no won­der I nev­er answer.
