An Idea For Your Accessibility Tab
It is extremely difficult to get a hold of the Microsoft Support Team if one does not have access to a phone. It is great to have the 'Chat' option, however, if one's account has been restricted for security reasons, one would think that the Team would use the alternate Recovery e-mail address as an option to be able to retrieve a code in order to regain access to one's account. Have you thought about people who have no ability to send you a text message? Food for Thought!
