This Domain is not supported or is already registered with Zoho

Yesterday I created a Zoho account and added my own domain (http://ihd-fs.co.il). However, I tried today config user on it but no successful.

I've recreated my account and I am now unable to add my own domain again to Zoho Mail. The error is This Domain is not supported or is already registered with Zoho

However, I deleted my old account, so I would like to be able to reuse this domain.

Could you please remove the domain from the Zoho system so I can recreate my account using my own domain.

Thank you,
Israel
