Qatar Airways — baggage mishandled and broken

Address: 339A 358, FLAT NO 303 VENKATAGIRI NIVAS 1ST CRO, 6th Main, 1st Cross, 560075

I have traveled from dfw to blr on 27th april 2019 where my baggage was mishandled and broken. After giving claim request qatar airways refused to take this. All the detail with image was provided with claim id dpr blr1763629. The reply i am getting that we can proceed with the claim because i have not reported at airport blr. This is frustrating to not accepting with have five star airline.
