Cultural Tip
In Brazil, consumer rights are protected by the Código de Defesa do Consumidor. Companies must respond to a contestação (dispute) within 10 business days, and you can also file a complaint with PROCON if the issue isn’t resolved. Using polite language like ‘por favor’ and ‘obrigado’ helps keep the interaction courteous.
