Dear Vidyadhar, you cannot retreive your hall ticket now. You cannot even download the admit card as the exam is already over. If this is about NEET PG results, please reach out to the helpdesk. Please mail them at nbeexamhelpdesk@gmail.com with the subject 'Grievance Ticket'. If this is for any other exam, please reach out to the respective helpdesk with the same subject line' Grievance Ticket'.
