Pass word reset

HI TO EVERYBODY 

I AM TRYING TO RESET THE PASSWORD TO E-FILE THE INCOME TAX RETURN. I DO NOT KNOW WHO ACTUALLY SET THE PASS WORD TO THE PAN NUMBER AND WITH WHICH E-MAIL ID.EVEN I DO NOT KNOW THE SECRET QUESTION. SO I OPTED FOR THE LAST OPTION OF SENDING MY PAN PARTICULARS TO THE E-FILING UNIT SUCH AS MY PAN NAME, DOB, FATHER'S NAME, MY ADDRESS. NOW I GOT THE MESSAGE THAT THE RE-SET PASS WORD WAS SENT TO THE REGISTERED E-MAIL ID. NOW MY QUESTION IS HOW CAN I GET THE FRESH PASS WORD? ACTUALLY I DO NOT KNOW THE  REGISTERED E-MAIL ID. WHAT TO DO? HOW CAN I COME OVER THIS PROBLEM.

THANKS IN ADVANCE.
