How do you deal with unsolicited and unwanted telephone calls?

We're talking commercial calls from marketing companies and other strangers, not your ex or someone close to you.

Tell them what they want to know

Be polite and say "no thank you"

Hang up

Put them on hold and don't come back

Make a creative excuse as to why I can't talk (tell us what in the next question)

Yell at them

Start to cry

Other (please specify) ->
