Please help me fix this! This Domain is not supported or is already registered with Zoho

Ok, so I reported it and seems the person attending it just quit without resolving my problem.

Im managing littmandrug.com.  its a pharma company here in the Philippines. 

My problem is, I couldnt use this domain due to the fact that it was registered.  I need to associate the domain in this account so i can configure the domain to point to zoho.  

Anyone in zoho that can help me?
