Delhivery — Non delivery of consignment and Negligence

My product was supposed to be delivered on 8th October. It reached my city on 5th but it’s not delivered yet. I went to to the hub to collect my package personally on 9th. The staff were not helpful at all. They said they’re trying to find my parcel as they have lot of shipments to go through. They promised to call me that evening so that I can pick it up. They didn’t do that and adding to that they sent it to a different delivery hub farther from my place. I’ll be travelling abroad and need that package delivered ASAP. Please resolve this at the earliest.
