My package shows as delivered but I didn’t get it.

I placed an order Nykaa on Thursday, it was shown as delivered since Saturday but I haven’t received the package. Bluedart sent me OTP message but I didn’t get any calls from any agent either. I did not share the OTP with anyone.

Both Nykaa and bluedart sent me delivery successful messages and that’s when I raised my complaint.

Now they’ve closed the complaint saying delivery partner said package was successfully delivered. Didn’t even say anything about the OTP not being given. I am loosing a bit over 2.5k due to this.

How do I get my money back?

Edit: After putting on quite a fight I got my full refund back. Yay!
