Like Maydup - plus many sites have a 'call me back' option, so someone can talk to you.
I agree with the frustration Lew - now here's an easy way to make up and remember a password.
Think of an important time or occasion in your life. Might be, when you got your first car. So you make up the phrase: I got a ford escort in 1970. The first digit of each word, beginning with a capital, would then become the password: Igafei1970
Now if a site is asking you to join with a password, ie become a member, before even giving you a basic quote, my reaction would be to shop elsewhere. But if you want that particular quote, you're gonna have to bite down on it and play it their way.
I'm used to faffing around with t'interweb and even so, their are times when sites get me to screaming point. Leave it. Leave them. Do something you enjoy. The internet is actually amazingly good.
