I paid for web hosting service, and they gave to me a domain (Private registered) I was deleted that account and I didn't use this domain ever. Now i found a new domain for a new site and i couldn't find satisfactory domain name. I can't login domain management account because I have already closed it. Can I get it back? Then How? Please help, thanks.
You should contact wherever the domain name is registered and talk with them directly. They should be able to help you and let you know what you need to do to regain access to it. Hope that helps.
Contact their Support Team, then explain to them what happened. If they are a good company, for sure they will help you.
