Organization ID: 644368849

This zoho mail account was earlier mapped to www.senacareese.com
I no longer own the domain www.senacareese.com
I wish to map www.pinakajewels.com to the same zoho mail account. 
Every time i try to do it i get the following error
"The domain pinakajewels.com appears to be already in use in another organization. Learn More"
 I am sure that pinakajewels.com is not associate with any other zohomail account. 
Please help me resolve this issue. I have already sent an email to support and my case number is 156030093
Thank you
