If you are talking about your online registration counselings then check your registration ID again and check your mail or inbox.

Sometimes server will be busy and takes time for response. Wait for a day and try again. Still if you are not getting OTP, delete few mail's and refresh and try again.

If any of them is not working, visit the College and let them know that you want to cancel your admission. They will do it for you
