How to cancel Gran Cursos by mail
Collect the details you need
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Gran Cursos is only as good as the details it quotes.
Put the request in writing
The request is prepared in Brazilian Portuguese (template pt-br), under the subject line “Assunto: Solicitação de cancelamento – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send it by certified mail
Send it certified to Brasília, Brazil, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
File the receipt with the letter. A Gran Cursos charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Gran Cursos, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
