How to cancel Smiles by mail
Start with your account details
Before writing, collect your member number, the name on the membership and the renewal date shown on your latest invoice. Smiles can only act on a request it can match to an account.
Write the cancellation request
Smiles is based in Brazil, so the letter goes out in Brazilian Portuguese, built from our Brazilian Portuguese template. Subject line: “Assunto: Solicitação de cancelamento – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post it with proof of delivery
Use certified mail for the 06455030 Barueri address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
Delivery confirmation is your evidence that Smiles was asked. Watch the next statement or two for any further Smiles charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a membership
Memberships renew on the anniversary of joining and may be cancelled at a counter, online or in writing depending on the organisation, so a written request names the member number and the end date.
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.
