Dear Harshad,

Please don't be upset. Check you email id for information provided to you by NEET platform and enter that only while filling your details. If it still doesn't work or it shows invalid details. Then you can contact NEET team through the contact details provided to you on the NEET website or on your application. You can call them by referring your details and complaint. Also, you can email them regarding your concern. You can find the email id on the NEET platform only.

Hope this resolved your query.

Good Luck :)
