@João Bonifácio Sorry for the painful experience!
Depending on your environment, you can cancel an Azure support plan with the following these steps:
- Navigate to the Cost management + Billing Overview page.
- Select the support plan that you want to cancel from the Your subscriptions page to open up the Support plan page.
- Select Cancel to cancel your support plan.

Note: If you are unable to cancel the support plan, you can reach out to Azure support by raising a support request with Azure billing team. The ticket enables you to work closely with the support engineers and get a quick resolution to your issue.

FYI: Azure Billing and Subscription Management support is included in the Basic Support Plan without any charge.
