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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
