Blue Dart Express — not yet delivered my courier through blue dart

Tracking number: [protected]

Through tracking On 14 th May 2019 item reached at adoor.till this date no one contacted me and not delivered properly.Today i searched through online tracking, and it's updated that returned to orginal at shippers request.
I dont understand why this happens like this and its not the first time.very bad service .
"Reached at Adoor .But not reached in adoor its in pandalam." No contact number nothing ...If i contacted to adoor blue dart .There is no proper answer.
I know that blue dart is one of the best courier service .But this type of peoples makes your brand down.
