Parcel delivery scam demanding OTP for non-existent order

"Someone called me saying my parcel had arrived, even though I hadn't placed any order. I told him I hadn't ordered anything, but he kept insisting it was my order and asked me to give him the OTP. When I refused, he called me again and again, saying I had to give the OTP. I said I won't give it, so he kept calling repeatedly and started threatening me. He also got his different friends to call and threaten me. I've filed a complaint about this on the cyber fraud portal. Let's see how long it takes for this to get resolved." contact no [PHONE]
