Hi Jose! My name is Darhyl and I’d be more than happy to help you with your query.

Just a gentle reminder that we are only Xbox gamers like you here in the community. We are not Microsoft employees and we do not have tools to access any Microsoft System.

Based on your description, it would be best for you to reach out directly to Microsoft Xbox Support as they have the tools and resources to properly investigate this and possibly update your warranty service order:
