How do you write a letter to bank manager for premature withdrawal of fixed deposit?

Write the letter in business format, with your address and the date in the upper right and the name of the person you are writing to and the business address on the left margin one or two lines below your address. Use a business greating, such as "Dear Sir:." Use business language to explain that you would like to prematurely withdraw the funds, explain your reasons, and you might want to ask about any penalties or other questions you may have. Close with a business closing, such as "Sincerely," leave a few lines for your written name, and type your name as at will be written.
