Tech Mahindra — Tech mahindra MCA registration

Website:

registration.techmahindra.com

I was first time trying to register Tech Mahindra drive, but I was notified as "You are already registered. Please login with your registration ID and PIN to complete/view registration." Though I tried with different mail Id and phone number the same problem persist. Please sort out this problem as soon as possible so that it would be help full for me to proceed with the registration.
