Mail the letter with a receipt

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.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
