Chaudhary Charan Singh University [CCSU] — Regarding cancellation of registration form

Sir/Mam i m sorry for the disturbance.
It's just like the cyber cafe guy has filled wrong registration form of mine which was for only U.G Law selections. I have not done the payment yet. But because by mistake my wrong registration form has filled now i can't fill that registration form that was for B.Sc. If i tried to fill that on the top of that is written 'this information (12th information) has already filled in another form. There is not even a option for cancellation of submitted registration form o[censored].G law.
And if i will not cancell my registration o[censored].G law I will not be able to fill the registration form of B.Sc.
Plz provide me some information what to do now as i want to apply for B.Sc.
My registration form username is 21G0202273
It will be very helpful.
Thank you
Yours sincerely
