I signed up in this site using facebook. In faecebook my age was wrong. That time I didn't noticed it. I want to correct my age. I already sent a mail to firstname.lastname@example.org. But they didn't gave any reply. What should I do? I don't know if I should post this kind of post in this section. But I don't know how I can contact with the proper authority now.. Any one have any idea what should I do?
