Hello,

It looks like your question is quite incomplete. You forgot to mention the college name ot any other details. Please complete the question in the comment box.

As for the contact number and email address you can visit the official website or you can visit your college gor guidance. Usually the diploma degree is granted after one year but as you have passed in the year 2001 you can collect it from the board of the examination.

For example in Delhi its Board of Technical Education so diploma students usually collect their certificates from there . Make sure you have college identification or provisional certificate to show to the authorities.

Hope this helps!!
