I never do business on the phone. If somebody wants to contact me, they can send me a letter. (The letter carrier may have a hear attack seeing an actual first-class letter - but so be.it.)
I hang up on unsolicited phone calls.
I got a text message once from the Conservative Party of Canada, asking if they could count on my support in the upcoming election. I replied, "No." A few minutes later, I get another text from them asking if they could have my postal code (presumably so they'd know what constituency I was in). I replied, "No." A few minutes later they send me the same text again and I replied, "No," again. Apparently they weren't set up for that response.
"Oh no, They've gone and named my home St. Petersburg.
What's going on? Where are all the friends I had?
It's all wrong, I'm feeling lost like I just don't belong.
Give me back, give me back my Leningrad."
