Insurance companies - specifically car insurance - are among the most evil companies.
Received an email from mine, renewal has increased by over £100 a year. But don't worry you can check and update your renewal using our website. Unless, of course, you want to cancel. In which case you have to call, and sit in a queue where they profusely, robotically apologise for how busy they are, and they're doing everything they can to answer your call. Everything aside from providing reasonably priced renewal quotes so that you don't have to extort them at cancellation, or allowing you to cancel online without having to speak to a specially-trained retentions department.
It should also be a legal requirement for this hold queues that I can sit in silence and only be spoken to by a robot when they're ready to talk to me.
