Thank you for posting. If you just registered the domain and don't see it in your account, it could just be that it's still processing. It can sometimes take an hour or more for a domain to appear within your account. If you've had the domain for a while, it could be missing because it expired. Try these steps to see if it's listed as an expired domain. Otherwise, we do have live support that you can reach by phone.
