There is one more thing that can be used as valid evidence. When you fill out the registration form, do you duplicate the form? Duplication can mean a screenshot when you fill in the google form and / or duplicate Google form sent to your email address?.

If you do not have the evidence as mentioned above, in my opinion, you have lack evidence to support your defense.
