Thanks for posting. Usually a WHOIS update posts in 24-48 hours depending on when it refreshes through the registry. However, are you sure it is the domain? Sometimes people have other products (privacy, business registration, etc). These show the domain name, but are not about the domain itself. You may want to check the account or have 24/7 Support do so.
I hope that helps,
