Dear [recipient's name]:

My Internet subscription's annual renewal date is coming up on November 16, 2010. As of that date, please cancel my subscription and refund any amount owed to me by mailing a check to the address listed at the top of this letter. I will return the equipment that I have been leasing from you by dropping it off at your local office as soon as possible after November 16th.

Please contact me if you have questions or need additional information in order to process this cancellation. Thank you for your attention to this matter.

Sincerely,

[Signature]
