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