wow you have same problem like mine. I had issue with police certificate. I DID mail Italian Police Cerf. and they gave me RFE. They told me that I have Serbian police cerf...not Italian one. #######? I never sent Serbian one...and I requested for Supervisor. They did review it and told me to wait 10-15 days. i gave up and decide to mail it again. Its not easy---its better for you to sent it again instead of waiting for supervisor review...its waste of time.
