What to do if a caller threatens to disconnect your mobile on behalf of DoT/TRAI

Department of Telecommunications (DoT), Ministry of Communications, has issued an advisory to citizens to not to take fake calls being received by the citizens wherein callers are threatening to disconnect their mobile numbers, or their mobile numbers are being misused in some illegal activities.
