If I need a copy of my divorce decree, how can I go about this?

Question Details:

I was divorced in 01/ 07/71. I have tried to get a copy 4 times. I am being told that they have no record of it. I am in the process of becoming an American citizen and I do need this form. Could you please advise me of what to do next? I have 3 weeks to come up with it.
