unable to create zoho mail

Hi ,
 I had a zoho account with username " nileshvatsa@gmail.com" ,it was deleted on 27th aug & then I recreated account with the same email id ,but now when I want to recreate zoho email " nileshvatsa@zoho.com"  which was associated with that account before deletion it says username is already taken ,how it's possible when I deleted my account,So please help me to get back my previous zoho username ,as without this there is no point of using zoho services for me,so please release my username associated previously with " nileshvatsa@gmail.com" i.e. " nileshvatsa@zoho.com" ,or tell me other steps to create same id.
Thanks.
