You need a simple reply letter:(posted 8290 days ago)Further to your letter of the xth month.
I have reviewed the contents of your form with my legal advisors. My understanding is that you have no legal right to this information and on this basis I am declining to complete your form. If your client believes they are entitled to this information, you should write further, stating your reasons.
By contrast I note that my requests for information pertaining to the claim your client is pursuing - which I am legally entitled to - remain unanswered. Specifically I draw your attention to my letters of the a,b,c,d,e, [list them all here]. I would welcome either the information being supplied, or in its continued absence the courtesy of an explanation for this delay.

If you want the information you should sarn them for it; otherwise always be polite but firm; just like they do, keep singing the same tune.
