FAQ's are infuriating!

What is the purpose of FAQ's? In 16 years on the Internet I have never encountered an answer to my question in the FAQ's. Indeed, there's no point in even looking at them.  Also when you contact a company they almost always force you to choose from a list for why you are contacting them. Unless there is an "anything else" option my query is almost always unrelated to any of the options. So I have to start off my query by stating my that query has absolutely nothing to do with the option I've chosen. Then I run into a character limit and have to delete this.  Doh!
