Fedex — No delivery attempt/shipment returned

Address:

Kankarbagh, Patna

Tracking number #[protected], reached Patna on 2nd July, today is 9th July 2021, no one came for the delivery, not even a phone call or a text message about the shipment. Finally I went to the FedEx office in Patna where they said the item is returned to the shipper because the address was incorrect, pin number was also incorrect which is not. Spoke to 11 customer care people but in vain.

At least they should have tried calling the number on the address and no one even called. While speaking to the unprofessional lady she said we have followed all the process and then returned the shipment. All I can say is everything is correct on the address but no one tried to deliver or contact the recipients in any way and finally returned the shipment. Please help.
