Delhivery — Shipment not Delivered despite multiple follow-up since 7 days

A pathetic and worst experience with Delhivery and their app is really useless. I had booked an Express shipment from Bangalore to Mumbai by paying the additional amount with the orignal date of delivery to be 1st Apr'23 and its been 7 days past that the package has still not been delivered. Everytime you open the app to check for the delivery status, the delivery date is pushed by 1 day. I even tried raising a complaint on the app but didn't get any response. I have been following up everyday but they simply push the date of delivery everyday.
A really worst experience with full hassle especially when i have paid an extra amount for the faster delivery.
Please see below the details with regards to my shipment:
