Delhivery — Not delivering the product and not responding to tickets

My order is reached final delivery center on 12th october 2022 and next day they changed status that it reached them on 13th october. Raised multiple tickets for prioritizing delivery but not even got a single response but they do mentioned they will respond back within 24hrs but didn't responded even after 3days. They don't provide mobile numbers for queries also. As it's delayed I asked them for warehouse address so that I can collect myself. When I went there, they asked to come next day and when I went there again. They carelessly respond and we can't find your item now, we will deliver it when we becomes free. It cost me around 60-70rs and 4hours of effect to go to their warehouse and listen all these nonsense. And the worst thing is they are asking us to not waste their time.

They should be responsible to the orders if they can't provide proper customer service then they should shutdown their service.
