Blue Dart Express Limited — regarding shipment issue

This is the 2nd time I am facing this problem with DTDC courier cuttack, odisha. A parcel has been sent by an online shopping site with tracking id [protected]. At the address of the consignee, everybody is present but they are updating in their site that consignee is not available. This has happened because the price for the item has been paid. They are careless and thinking that consignee will go to the courier office and collect it. In case of cash on delivery they deliver it but why not as the payment has been already done. When i call them on [protected], they did not even recieve the phone. I searched on internet i find a lot of complaint regarding the shipment issue against this courier provider. This is a serious issue as everytime they are doing like that so if something can be done seriously please do
