Write a letter complaining against an Insurance Policy.

Dear Sir/Madam

Complaint Policy number (----)

I am writing this letter as a follow up to my earlier letter dated (date). For your kind information, in the earlier letter, I had asked for details of the cash-in value of the above investment.
I have received your reply and am concerned to find that,despite having paid (amount) in premiums, I will get back only (specify amount) if I stop the policy now.

I would appreciate it highly if you send me a detailed breakdown showing how you arrived at the (amount). I can say with certainty that there must be some error in your calculations. Kindly send me an early reply regarding the matter.

Sincerely,
