@samuel lacerda We cannot completely understand your question as this is an English global support. It would be helpful, if you can translate your question in English.Or you can consider support in other languages from here: https://azure.microsoft.com/support/options/
Refer the FAQ here: For which languages does Microsoft provide support?
After translating your question, this is what I understood: Issue with the Azure Subscription credit.
When you sign up for an Azure free account, you get a Free Trial subscription, which provides you $200 Azure credit in your billing currency for 30 days and 12 months of free services. At the end of 30 days, Azure disables your subscription. Your subscription is disabled to protect you from accidentally incurring charges for usage beyond the credit and free services included with your subscription. To continue using Azure services, you must upgrade your subscription. After you upgrade, your subscription still has access to free services for 12 months. You only get charged for usage beyond the free service quantity limits.
Once your free services and quantities expire, you're charged pay-as-you-go rates for any services you're using. You can use the Azure portal to delete the resources for the services that you don't use. If you don’t intend to use any Azure service.
