Dear Jimy Ortan,
I wish to cancel my membership in this cooperative effective May 1 of this year. Kindly stop sending me newsletters as well. My member ID is 321ABC. I have already settled my dues and balances until April 30th. As indicated in the written agreement, this letter is enough to process the cancellation.
Sincerely,
Yashina
