Capital First — harassment and threatening to the family

Im neither a first capital customer nor a person who has applied for request. A person called me today ([protected]) stating that he will take my mobile if i have not paid the bill. He didnt introduce himself and from the beginning he was using abusive language and shouting. He is threatening me that he will come to house and harm my family also. Im wondering why the company has gundas and targeting women who are not their customer. If the team has gundas in their group, they should really have concern. When i received the second call, that time they introduced that they are from first capital. And till the end they didnt explain how they got my number and why they were shouting in the morning hours. I would request you to dissolve this gundas members and take appropriate action.
