Dear [recipient's name]:
I am writing to notify you that I will be canceling my membership to Winners Athletic Club when my annual membership ends on July 31, 2010. Please discontinue charging my credit card for the monthly membership fees and for any other costs after that date.
I will return any club equipment that I have, including my locker room key, before July 31. Please send me a written confirmation of this cancellation so I know that this will take effect on July 31. Please also let me know if there is anything else I need to do to make my club membership cancellation official and effective. Thank you for your prompt attention to this issue.
