Sadly without a solicitor and court action they just laugh at you...

You might be surprised............they hate publicity about lax security, and very often a simple mention of this will mean they will start to get very helpful!
Its also well worth remembering that its very easy to take action in the small claims court, and while small claim isnt relevant in this case, in the face of court action for small sums there is a good chance a big company will simply pay up.
