Blue Dart Express — in spite of giving the correct address I am not receiving any of the shipments

Address:

500090

I am not receiving any of the shipments. When i tried to ask for the reason, they were giving me the answer as flat number is not available. However i am staying in an individual house and address is sufficient. My house itself is a landmark as there is a reknowned play school at our area. And i am residing above the play school. I missed my kotak cc, scb cc, my insurance hard copy... The list goes on. Now i have another shipment came and that is also having the same status. I went personally to the office and they said they don’t have people to check the address. I am fed up with the servic and i am requesting the bank authorities also to not to send the bank cards via blue dart. I am not sure whether to provide my details.
