Hi! My name is Aj and Im an Independent Advisor here to help! Im sorry to hear about your account. Since you do not remember the email or password, the only option is to try Microsoft's account recovery form at https://account.live.com/acsr and provide as much information as possible about your account such as old passwords, subjects of recent emails, Xbox or Microsoft services used, and billing information. Microsoft support uses that to verify ownership when the security info is not working. Also, use a device / location / network you often used with that account. You can submit up to 2 forms a day, guesses are okay. After submission allow 24-72 hours for verification.
