How to cancel Claro Internet by mail
Note your account details
Put the account number, the phone number or service address being cancelled and the name on the account in front of you before you write: the request to Claro Internet is only as good as the details it quotes.
Put the request in writing
Postbye drafts the request in Brazilian Portuguese, the language of Brazil, with “Assunto: Solicitação de cancelamento – [your name]” as the subject line. It asks Claro Internet to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Address the envelope to Claro Internet, Sao Paulo, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the proof of delivery
File the receipt with the letter. A Claro Internet 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.
