India Post — Delay in parcel delivery and not getting any update

Consignment number EK[protected]IN was booked on 9/5/233 from Bannerghatta road post office Bangalore. Destination is Mumbai.
In tracking it shows last update on 11/5/23. After that no updates on tracking site. I registered complaint on Indiapost online forum but no result.
