@MojangSupport Can't answer the security questions, and don't have access to the email that the account is tied to in order to reset them. Can't migrate my account because apparently the username is invalid.

As I said, I don't have access to the email tied to the Minecraft account. No access to the email means no access to the transaction ID.
