Recursos do Microsoft 365 que ajudam os usuários a gerenciar suas assinaturas, configurações de conta e informações de cobrança.
Hello Rosa ,
Thank you for posting on the Microsoft Q&A Support Forum.
Based on your response above, I will suggest that you contact Microsoft Live support using this link Entre em contato conosco - Suporte da Microsoft
Provide prove of charges and let them know that you’re being billed monthly, your subscription doesn’t appear in your account, and You can’t access Office apps. You will be guided on the next line of action.
I hope this helps with your concern.
Best Regards,
Odinaka | Microsoft Q&A Support Moderator
