Cancelling a rental or lease agreement
Rental and lease agreements run to a fixed term with return conditions, so the request should name the agreement, the date you want it to end and how and where the item will be returned.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
