I’ve had some real howlers the other way though (with actual scammers) so I understand the frustration, one woman who was obviously a spam PPE caller yelled at me “don’t you like money!” after I had politely declined,and there’s no dealing with that.

If I can, I keep them on the phone until they hung up on me frustrated. More often than not I can, I used to wfh and be able, in between meetings, to keep them going for a while, while doing my actual work. “Can you spell that url again? No it says page not found” or “of course I want a refund for that iPhone, what do I need to do”. All while typing my work emails, chatting with colleagues or working on a slide deck. Nowadays I’m looking after young babies full time. So even easier to apologise for the background noise and ask them to repeat their whole spiel for a fourth time.
