Blue Dart Express — waybill not received

Address:

Borjhar, Kamrup Metropolitan, Assam, 781125

My product with waybill no.[protected] is not delivered yet and the expected delivery date is 18 january 2020. And today its 19 january 2020. Blue dart has not contacted me not even once and without informing me anything nor contacting me, they showed the status as"no such consignee at the given address" what a nonsense way of service. I tried contacting them and they say their lines are congested and so no response. I visited the courier centre and they said they know nothing about my order and that have not received anything such. Are they gone mad their own website is showing me the status that my receivable product is in the airport of my location and what the hell they are saying me. I am totally disappointed and angry. I will wait for 3 days and after that am gonna sue or file a case again the company. Its a serious issue and my product is too important for me. I am really gonna take the help of law if the status remains the same.
