Hello Aspirant, hope you are doing good.
The fact that you have forgotten the basic details like registration no., hall ticket no., and application no, you have to call the concerned authorities through the helpline desk number given in the official site. They will ask you the necessary details to verify your account, and only if it's verified , then you will get the details.
Also, you can check your registered email and phone no., and check for the message that has been sent to you when you first registered, check your spam folders as well.
Hope this helps you. Good luck!
