If you believe that a web site is misleading then you should contact the Advertising Standards Authority. Their web site (www.asa.org.uk) gives you details of how to make a formal complaint.

If you have purchased insurance through the web site, another good remedy is to write to your insurance company. Address your complaint to the Compliance Director. They will formally acknowledge your complaint and investigate. They do not have a formal responsibility for policing their “retailers” but in all probability they will be interested, as they will not want to be associated with any site that misleads.
