Jiomart — Fraud by delivery executive

I ordered JioDive from jiomart. On the day of delivery the delivery personnel called me and said that he is at my house. I was in office so I asked him to deliver it to the security personnel and he then asked me the OTP to deliver it to the building security. Once I reach back home the security personnel told me that no delivery person ever came. Now Jiomart team has told me that it's not their responsibility what thier delivery executive do. The customer who has already paid for the order is responsible if the theft is done by their delivery executive.
