Blue Dart Express — I'm complaint about the irresponsibility of Blue Dart Courier service

The estimated delivery date of my parcel ( [protected]) was on 4th September 2023. The parcel reached the destination city on 8th September and I thought I would receive my package soon and I continuously kept on tracking the status and finally it was changed to contact customer service. When I contacted them they told me that they couldn't detect where my parcel is and they aren't recieving any response from the team. Today is 14th September and till now I haven't received any msg or call from Bluedart. I have already paid the amount for my parcel and the sender is not responsible if the parcel is lost hence I can't ask for refund to them. It has been 6 days and no further move is initiated, this shows the irresponsibility of the courier service and they are playing with the customers patience. If in case my parcel is lost then necessary action should be taken and refund must be given.
