Passport Office Bangalore — reissue passport delaying

I am praneet (Minor) from mysore. I applied for reissue on 9 nov 18 in mysore. But after 2 month, i did not receive it. Then i went to kormangla office with my mother and all original documents on 14 jan19. There ve found that ma big mistake done from mysore passport office (Attachment of different person's document with my form). We met dpo sir there. He told me to submit all original documents and one photo for uploading directly to the computer. He told us, passport must reach within 7-10 days. But till now i did not receive anything. Please tell me the reason for delaying...
