Cpt registration help

I am student, willing to appear for cpt june 2017 attempt

I have filled the online form for CPT june 2017 and the payment has been made through online gateways. I have received an acknowledgment number. I have sent the application form after attesting the  required documents through speed post, but I have not got any further details on my registered email or mobile number regarding user name password or registration number.

I dont know what to do next so as to fill my exam form
