So, TRAI has recently been announcing this over all phone calls that scammers are using International Numbers to call people and telling them they have a parcel under their name with their Aadhaar number and it might be something illegal to lure money from you.
They will connect with you to a "police officer" or a "customs officer" to make you believe you are part of an illegal activity and scam money.
Don't fall for this. If you get calls like this immediately hang up or talk to someone.
This is a video of the how it happened for me.
