Date of birth correction

I have written my matric on 2009,I had no birth cirtificate by that time, the process of the application of a birth certificate was ongoing by that time, so after the result came out I found out that my date of birth is incorrect on the statement, i went to the department of education to correct it, they told me to wait for a senior certificate, when the certificate came out i went to the offices again, they told me that they are not correcting them yet, they said they are still busy with the old syllabus ones since i was on the new syllabus, so they gave me a number that i should call to check if they have started with the syllabus That i was doing, so I called now and then to check that, and at last they told me that i should come, i went there with the documents that they have to me to bring along, the person that I found said that they are no longer correcting any certificates for my syllabus, so there is nothing they can do, they told me that if ever I need to apply for something i will have to write an affidavit at SAPS and attach it with my application every time. Is it possible for me to correct it
