Stamp duty exemption

Dear Sir,

I am an ex servicemen retired from Indian Armed forces  in 2003, last year i purchased a flat in Visakhapatnam worth of 34 lkhs( Goverment Value)  and paid stamp duty as per rules in andhra pradesh.

I came to know that the stamp duty exempted for ex servicemen, kindly advise will i get back the paid stamp duty? if so what is the procedure.

Best regards

Ravi Kumar
