Hello aspirant

hope you are doing well and safe. With reference to your query,  I would say firstly you dont need to panic . Stay calm and take deep breath . Mail the higher authorities with your username and ask them to provide credentials of this user id as time is very less . They  will revert you through mail with your password and meanwhile you try to reset your password by clicking on the forget password

Hope you found this answer informative. Best wishes for your future
