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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
