I was in a car collision and need proof of my location when I called 911. How can I get this info. from my i phone device?

I was in a car collision and need proof of my location when I called 911. The Police Dept., refused to respond, since there were no injuries.

Now, I have a dispute with the other driver who is falsely stating accident happened at another intersection. In addition of calling 911 twice, I also took pictures of damages. Unfortunately, I did not take pictures of the intersection signs.

My AT&T carrier states that this info. can only be disclosed by a subpoena. My insurance carrier states that they will not subpoena this info., since it is a civil case only.

The Police Department does not keep records of calls they do not attend to.

How can I get this location info. from my i phone device if at all possible?

Thanks,

Pecosa
