Blue Dart Express — not delivery at my apartment

Address:	620001
Website:	Bluedart express delivery

I ordered lg 260 l refrigerator from amazon, which was delivered to me via bluedart, waybill no. [protected] on date[protected]. And the bosch 7kg washing machine, waybill no. [protected] delivered on date[protected].
The men who came to deliver it left it on the ground floor of my building, even when i asked both of the bluedart staff that the flat no. Written on the delivery address was on the second floor. I repeatedly told them separately that the address is on second floor but they both left the things on the ground floor unsecured.
I live alone at my place and want my things to be delivered at my apartment exactly, otherwise i cannot lift it to my address alone.
If you claim, bluedart is door to door delivery, it is against your policy to leave it unattended.
