Blue Dart Express — non delivery of medicine

On 21.03.2020 i have booked a consignment (Waybill no : [protected])
Through bluedart at erode, tamil nadu to los angles, usa. But i am
Sorry to say that the consignment has not till reached the recipient.
The very purpose of the consignment was sending medicines. After long
Back, it seems it reached usa and when i tracked online it says that
On hold for regulatory paperwork. One month back, the recipient was
Asked to pay $100 to further clearance and that was also paid. But,
Still the consignment did not reach. Please look into it
