Blue Dart Express — consignment not delivered timely

In manikpur, district : bongaigaon, assam service is pathetic. My consignment with tracking no [protected] reached your office on 16th august, 2018 but till today item was not delivered. The entire day has been wasted just waiting for him to deliver the package.. I have dealt with a lot of courier companies but honestly this is the worst.
They have the mobile number but they don't bother call, i had to go and collect the product from bluedart office.
