Outsourced IT
I once logged a ticket to complain my email client wouldn't open (in the awesome days of 2007 when I was still forced to use Lotus Notes). We had outsourced IT support, since the company IT guy had managed to turn himself into a project manager for something else about 6 months earlier.
I didn't hear anything back for 4 hours or so. Eventually in frustration I logged into the web-app (on someone else's PC because it wouldn't work on mine) to get access to my emails... the idiots had sent me an email asking me if I had tried rebooting my computer (and no, rebooting hadn't fixed it the first 3 times I tried).
I may have complained. A bit. Loudly. With four letter words.
