Delhivery — Delay in Delivery of Courier

My courier with tracking ID[protected],[protected]
Why is it taking so long to deliver, as the ETD was 4th July, and it's stuck at the same place from last 8 days, I also visited the warehouse on 6th and 8th July, but they don't even talk to us, the warehouse manager Krishnan Majumdar (Cnt - [protected]) is so rude, he don't even pickup the calls and has also blocked me on whatsapp.
There isn't any toll free number of Delhivery and also I did filed online complain on delhivery website 5 days ago with ticket id 42106946, still didn't got any reply, also have mailed at customer.[protected]@delhivery.com, it was also of no help
please help me in getting my courier
