How to cancel Serasa by mail
Find your account details
Serasa will look your account up from what the letter says, so check the account or subscription number, the email the plan was bought with and the address or devices it covers first.
Prepare the letter
Because Serasa is dealt with in Brazilian Portuguese, the letter is written in Brazilian Portuguese (template pt-br). Subject: “Assunto: Solicitação de cancelamento – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Post it with proof of delivery
Mail the letter by certified mail to the São Paulo address in the next section, and keep the tracking number.
Save the tracking record
Delivery confirmation is your evidence that Serasa was asked. Watch the next statement or two for any further Serasa charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
