RTO India — DOB mistake in in my 4 wheeler DL

Hi,

During my 4 wheeler license application, I submitted my aadhar which has correct DOB. But I got my DL with wrong DOB [17/06/1972].

When approached RTO to correct it then I got to know that it can not be corrected, I have to apply new one.

As a consumer, why shall I suffer and pay money again to make new DL.
Why it can not be corrected based on passport/Aadhar? Are they not valid documents?

Pls help.

Br,
