Hello,
Enterprise memberships go through a very thorough review, and it is expected that they will take time to be approved.
That said, if you need support for your enrollment, you'll need to contact us or reply to your existing case.

Account specific matters fall outside what the forums are able to address, since these forums are focused on software and accessory development questions and we do not provide support for individual account or membership status for privacy reasons.
Best regards,
Developer Support
