CashBean — i am complaining about the person name neeraj who said he is calling from cashbean

My husband would have taken loan from cash bean for which i was unaware. Today i got a call from a person named neeraj from cashbean. He started talking to me with no sense of talking to a customer. His language was threatening and highly insulting. Out of courtesy, i told him that i was unable to take his call earlier since i was busy taking class. For this he replied to me what kind of teacher i am.. He has chosen a perfect day of teacher's day to insult a teacher.
