HI Kumar, Send mail to firstname.lastname@example.org describing your problem. Mention your name, candidate id, exam date in mail. If your postal address is not correct, or if you want your certificate sent to a different address, please login to your files at the i-7 cert tracker database http://i7lp.integral7.com/sun and update your address, then send email to email@example.com.
On your way in you may have missed that we have a policy on screen names here at JavaRanch. Basically, it must consist of a first name, a space, and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it, which you can do right here.
