Did you remove the domain from the account before suspending it?
Accounts arn’t deleted straight away, so you should be able to reactivate it, and either use the domain there, or remove the domain freeing it up for your use.
If you’re having problems logging back into that account, you’ll have to wait for Admin to come on and he should be able to help you further.
Actually I have deleted the account, so I m not able to access that.
(Deleted accounts are accounts you’ve had in the past that have since been removed. Deletions are permanent — neither the account nor its contents can be recovered in any way.
When an account is deleted, all its domain names are released and can be added to other accounts.)
