Tech Mahindra — Registration process Problem

Good morning mam/sir,
This is jamuna. Sir /mam actually today I filled my details for tech Mahindra online exam, while submitting I received a pop up message like your not eligible (because I filled my 10th marks in points like 9.5 instead of 95%), then again I thought of registering again because there is no any edit message, while 2nd time its showing that you had registered already check your mail for I'd, but till now I did not received any mail regarding to registration, so please what is the alternative for this problem Iam willing to register & attend for the online exam.
Today is the last date for registration also.. Kindly I request you please mail me the solution for this problem. How can I register successfully. Please I request you help me for this registration process.
Thanking you sir /mam.
