Cancelling a credit card
Card issuers close accounts only once the balance is settled, and recurring payments and rewards are tied to the card, so a closure request should name the account and say what should happen to each of them.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
