VSTS - Recover the team project if deleted

Hello there,

I recently setup VSTS in my organization, Would like to know the process of recovering the Team Project if it is deleted.

Whom should we need to contact immediately if it is happened.

I went through this url which was not clear whom to contact, what to do. but we can get data 30days old only.
