Final answer:
To close an account with a cooperative society, write a polite and clear letter with your account details and reason for closure. Use 'Sincerely' for a formal letter closing or 'Thank you' for a semi-formal approach. Sign the printed letter above your typed name.
Step-by-step explanation:
To write a letter to a cooperative society for closing an account, it is essential to have a concise and polite tone. Your letter should have a clear subject line, such as 'Request to Close My Account,' and the body should include your account details and your reason for closing the account. Make sure to include any necessary instructions or requests for what to do with any remaining balances in the account. For the closing of your letter, it is common to use 'Sincerely' as a formal salutation, followed by a comma. However, if the letter is semi-formal, 'Thank you' can also be appropriate. Remember to leave two lines blank after the closing before typing your full name. This space is reserved for your signature when you print the letter out.
