Ola Cesar, welcome to the community !
Log into your Azure account and use the Azure Cost Management tool to review all the resources you have been charged for. Verify if the resources you attempted to delete are still running or if there were other resources you may have overlooked that incurred charges.
You may need to contact Azure Support immediately. Explain the situation, including your attempt to delete resources, the unexpected charges, and any circumstances that may have prevented you from managing the resources as intended.
