Write the cancellation request
The letter asks Instant Checkmate to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Instant Checkmate”. Postbye fills it in from our English template.

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.
Instant Checkmate lets you cancel directly (online (Cancel Subscription form) or phone). A letter is the fallback that leaves a dated record when the direct route fails.
