Wrong date of birth in Police certificate

I'm Benjamian D, Blay Jr. and I applied for a police clearance in Ministry of Interior Director of Criminal Evidence and Information Department in Doha, Qatar through a representative last May 4, 2011 and they release me a police clearance last May 11, 2011 but I found out and the Canada Embassy here in the Philippines that my DATE OF BIRTH is wrong instead of NOVEMBER 27, 1983 the data in the police certificate is November 17, 1983. Could you give me some information on what to do on such situation, they based my information on my PATAKA which is also have a wrong data of DATE OF BIRTH. But I have a lots of Document submitted to prove my Right Date of Birth including my latest passport, my working permit here in canada, my fingerprints authenticated here in canada and my NSO Authenticated Birth Certificate.
