How can I get the Judge to Dismiss my case for refusal of a Chemical test when I didn't and no one will listen?

I was charged with a Blood Test Refusal, but I never Refused. I did however refuse a Breathalyzer because I was afraid it would affect my pacemaker. The cop had me read and sign a 1547 form in the interrogation room, that said if I refuse a Blood Draw I would be charged with the max for DUI. I read it, signed it, got a copy of it, and waited for the Blood Test. He then released me. 3 days Later, I found out he filled out the affidavit stating I refused the Blood Test. I DIDN'T. He never took me to get it. On My copy of The 1547 The Affidavit section is Blank. But he Submitted his altered copy to PENDOT and The Court. I found out later he was supposed to read it to me in the presence of a witness and then have me sign it. There was a Video Camera in the room but they wont release the video
