Hello aspirant

Hope you are doing great there . I am sorry to say this but your question is quite different . For this I would suggest you to calmly try again and carefully fill your details , since it might be due to some error by you in filling  your details at the time of checking result . Next if this does not helps , Then I would suggest you to contact the NTA query centre immediately , Since no one else can help you in this.

I hope my answer helps

Wish you all the very best!
