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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
