I got a call at 10:40 A.M. on 3-Dec-2018 and the person(Male) on the other side claimed to be an immigration officer. he was harsh and constantly yelling for no reason. he seems to threaten saying 'Do you know what it is to get a call from immigration office' and demanded me to listen carefully.

I GOT SUSPICIOUS and asked him to call me after office hours without providing any details (again harsh BEHAVIOR) so that i can gather information if this is genuine.

It turns out it was fake call. will update information if he calls back. i was wondering how he knows my name though?
