i'm sure that my custom domain doesn't exist in your services and my dns set on other servises(ns1.gigfa.com,ns2.gigfa.com).
background
I won't to be sutcom.ir in your services. it mean I buy Host from gigfa.com and set my custom domain here and in http://www.sutcom.ir no problem but http://sutcom.ir redirect your server.it seem your server have my domain information and don't allow tha delete my custom domain.
i saw that i have deleted my hosting account (sutcom.zxq.net with attached domain sutcom.ir) and to access again my configuration to delete custom domain sutcom.ir ,recreate on and there's no custom domain and not allowed me to add sutcom.ir and show the message
"domain name already exist" while by deleting hosting account remain in configuration.
