Messaged you now sorry for late reply @holydarkness
Uhh... I am actually hoping for the subject of the email, so I can tell my contact that a player with xxx email address wrote you an email with xxx as a subject, attempting to do manual KYC. BC usually use UID as their identifier, not username or email address, but I figure that you've gave it to BC.Game Support when they asked you that.
Anyway, I'll reach my contact, see if the email address is enough to get them to zeroing into your message to them and initiate the manual KYC... I am arming myself with a wooden stick to get them to do this ASAP. LOL.
Wishing you best of luck and for this issue to be cleared within couple of hours.
