1) Many banks or telecom companies use Recovery Agents to collect their old dues instead of filing cases.
2) Some of these dubious recovery agents makes a fake call that a non bailable warrant is issued against you. Or pretends to be a police officer and asks you to contact a given number.
3) Frightened person contacts the number who pretends to be a lawyer or a clerk of some lawyer and asks him to settle account with bank or telecom company to avoid arrest.
4) Many people get frightened and pay up the claims or bills even if the bills or claims are disputed.
Steps to which can be taken.
1) Check origin of number on caller identification apps on internet.
2) Ask for specific details about caller and case numbers.
3) If caller asks you to pay up dues of some bank or some telecom company, then send and email to them asking if they have authorised this call or not. Ask them specific details if they have filed any complaint or case against you.
4) Seek advice of your lawyer.
