Cancelling a security or identity-protection subscription
Security subscriptions often auto-renew and monitored plans can sit on a fixed contract term, so it matters when the request reaches the provider and whether it covers every device or location.
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.
