Need Help! blocked from Vault Insider

So I couldnt find anywhere to message for help, but when i signed up for insider it asked my age and i put in 1/1/1919 and then I got a VERIFY YOUR AGE with a privacy policy button and its locked me out, I went to my profile and saw it put me down as April 2019, but even after changing it and having the Shift account now say 18+ I still get same notice when trying to sign up
