xbox enforcerment page

I already spoke in the chat, and it is definitely a failure of the page, I have sent the report through the xbox support page, I would appreciate if you do it too, thanks for the support!

That is correct, it isn't possible to contact them through any other method. It is possible that you've been banned from all Xbox Live services, which isn't allowing you to access the Xbox Enforcement page. I recommend you to try to access using the Private mode of your browser. If that doesn't work, then it's likely you can recover your account.

I already did it with different browsers, devices and even another Wi-Fi network, I still cannot enter to review my case, it is frustrating I have no idea of ​​the fault that I have committed whether it has been fair or not.

What option would allow me to start a chat? , by clicking the contact us button it gives me several options

I see. Unfortunately, these sort of issues happen from time to time, but as a Community member, we don't have much more information about the status of the Enforcement page. I recommend you to contact the Xbox Support directly or the Microsoft Support through the page https://support.microsoft.com/ContactUs and then on the "search page" you can press on Contact Support. You should be able to start a chat support.
