Tech Mahindra — Didn't receive registration ID and PIN

I had registered for tech mahindra off campus and I fulfilled all the details in a registeration form, I have entered my CGPA instead of entering percentage, I did not get any mail from your side for confirmation of registration, please sir sort out this problem as soon as possible so that it would be helpful for me to proceed with the registration process, please consider my application as I am trying hard to get place in your company.
