Delhivery — Delivery didn't happen and now return also not done

I booked a package to deliver from bangalore to howrah on 3rd oct. The parcel is stuck in Bangalore since 4th Oct (10 days now) .

Asked for a predictable date from customer care and all the time got a messages please wait for 48 hours for the update and no update . This happened 2 times and then customer care also stop replying emails.

Asked for return so that I can deliver it via another vendor,
Now the return is also stuck and the automated messages says
"We could not deliver your Delhivery Direct order with AWB[protected] and it will be returned back to your address by[protected]T23:59:59."

today is 13th oct and their return date is 9th . send another email and raise complaints, no response again.

Everything got silent and no return movement also happening.
