I have one Windows machine in the house, which I take good care of, and a bunch of Macs, Linux boxes, a FreeNAS system and a couple of Hackintosh NUCs on the TVs. Last time they called me, the Windows box wasn't even switched on, and I was sat in front of the TV in the lounge. I played along, but when they asked me to press the shortcut for Run, I didn't best impersonation of a panicked non-tech person, moaning that it wasn't doing anything and they were right but maybe too late to help me. They told me to open IE, oh noes! It's not there! They asked me what keys were on the bottom left of my keyboard (to filter out Mac users - nice touch, albeit somewhat late in the script) and I told them exactly what I saw on my Logitech wireless board. Utter confusion followed - they seemed to have chanced on a PC that was so utterly borked they couldn't do anything to demonstrate how borked it really wasn't. They escalated my call to a manager, who finally asked what was at the top left of my screen ("Well, there's a little apple and...") after a long pause, the first guy came back on, said "Hello, Sir? Go to hell, sir." And he hung up.
I was left with mixed feelings - of course these guys are scammers and bottom feeders, but the anger in his voice revealed how hurt he was to have wasted his time (which is money). Yep, got my own back, and maybe made him think, but ultimately these scammers aren't doing it for giggles, they're doing it because it's a way to make money, and presumably their English isn't good enough to work in a more legitimate call centre. I can afford to mess these guys around for the better part of an hour, but if he's on performance related pay, coming up to the end of a shift and wastes his time on me when he could be wringing a couple of sales out of people like my parents, I've just cost him big. On the one hand, I'm delighted to be doing my bit to slow down the success of the scam, but on the other, I'm depressed to live in such a shitty world that an (at least) bi-lingual dude of around my age is sat in a call centre somewhere in India, extorting his way to paying the bills and putting food on the table.
I dunno what the solution is, and maybe it's ridiculously post-colonial of me to assume the guy's poorer than me. Maybe his shitty scam job earns him £50k and he drives a Merc, but ultimately I think this kind of vigilante approach solves nothing for anyone. We probably all ought to pressure people in power to do more to address the issue.
