Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
