In a reply to my submitted proof of No Claim Bonus I received a very pompous response demanding the submission to be on a company letter heading, which was the official stationary of the company, incorporating it's trading name, registered office, company registration etc. In addition it demanded my home address be displayed which admittedly was only registered as my post code, however it corresponded to the post code on my insurance application, registered at least twice during the application procedure.This letter went on to make a number of threats unless I complied promptly, the whole tone totally inappropriate and disturbing, giving me cause to rethink if I still wished to pursue the application with such a company
