DTDC Courier & Cargo — product not delivered

My consignment number is Z73766255 dtd 13/10/2018, and my package is not delivered at Pilibhit City, U/Pradesh. From last three days, it is showing the same status. and 16 days have been passed since it arrived at Bareilly. I called customer care but they are not telling me why my package is not delivered and they give some other number, which are not attended even after hours of call. You can feel my frustration, as this was my first experience with DTDC. I am regretting, why i chose DTDC.
