Wrong keyin telephone number when verify and cannot rollback or register again

Wrong keyin telephone number when verify and cannot rollback or register again

Good day Zoho Team,

I registered my domain themanna.vn with Zoho system for email hosting

To verify the system account I user tel number: +84906955339/ email: 
themannaviet@gmail.com

 However, I had keyed in wrong tel no as +84906955399. That is a reason I couln't received the verify code on +84906955339

The problem that I cannot registered again the domain themanna.vn with Zoho, I also cannot control anything because your zoho always issue "* This domain is already associated with this account "*****99"

Could you please help me to delete the record or give any action sothat we can register the  themanna.vn with zoho email system

Thank you and best regards,
Simon
