Abn Amro — abn amro credit card department

Address: Kolkata, West Bengal, 700075

My father has taken a credit card for ABN AMRO 10years back.
He could not pay the whole outstanding amount, however he have paid some amount and for the remaining amount our lawyer sent a letter to the bank that he cannot pay the whole amount. We can come to a settlement. Now someone from bank named as Rakesh (ph no. [protected]) is constantly harrasing me. He has called up to some people in my office and said that I am facing some financial legal matter. Whereas the loan was Not taken at my name.
My father is already ready to do a settlement in installment basis. But the man is forcing us to pay the amount by tomorrow. We are asking atleast for 15days time to start the installment. But he is constantly threatening me. How can someone harass a girl in this way? When the defaulter is ready to come to the settlement.
Can someone please help me. My email id [protected]@gmail.com.
