Mastercard and C6 Bank Provide Updated Customer Contact Details

Mastercard Brasil has refreshed its consumer support channels, directing users to an online contact page (https://www.mastercard.com.br/pt-br/consumidores/suporte/contato.html) for inquiries, complaints, suggestions and career opportunities. The portal lists links for contacting card issuers and a dedicated “Carreira” section for job applications.

C6 Bank, a fully digital bank, outlines its customer‑service options, including a 24/7 SAC phone line (0800 660 0060), WhatsApp, and in‑app chat. The bank stresses security best practices, advising users never to share passwords and to use the official app chat for most issues. Both institutions aim to streamline support for cardholders and account holders across their respective markets.
