This is kind of the reverse of the much more commonly occurring 'man recorded threatening to kill Microsoft Support staff'.
I'm at the stage where if the name on the call display isn't someone I know I won't answer it. Legit business will leave a message. If they don't then it's some asshole from some sales gimmick, some bullshit charity*, or the goddamn Conservatives** phoning again. Fuck 'em all.
* we donated once to a charity over fifteen years ago when we left the old house; no matter how many times I tell them I don't have anything to donate now they still phone at least four or five times a year, like I build up enough clothes every three months to give away. GRAB. A. FUCKING. CLUE. ALREADY.
** I asked the Tory fundraiser that called why they were doing sweet fuck-all to help Albertans being destroyed by the oil price drop, after we've financed this country's spending for the last decade, and why they thought the sanctions against Russia wouldn't also end up clobbering us at home when Harper and Obama quietly encouraged the Arabs to open the taps up full to undercut Russia's main source of revenue; I snarkily 'apologized' to them for not being able to donate to their election fund this time around because I was probably going to be homeless in a couple of months; they said they'd get back to me about 'my concerns', fuckers still haven't called back though for some unknown reason.
