Postal Life Insurance — no policy documents available

I took a pli through aps. It was taken through a lic agent. My policy number is 334141/301/lc. I started the policyin 1998 and paid until 2006. When left army, was unable to continue policy as i could not transfer to civil postal service, because did not have any policy documents. If i can get the documents will help me to transfer or terminate the policy.
