Since my mother in law took loan from bank but was unable to even pay it's interest on time

Since my mother in law took loan from bank but was unable to even pay it's interest on time so the employees of bank would visit my husband house to get their payments then my mother in law would cry infront of them then they will return back feeling bad. I somehow managed to save money and told my husband to pay that debts. My husband went to pay the debts and asked how much money he should deposit to clear the debts then the employee's of bank humiliated him that he always asks about that but he never pays. He told that he is there to clear all the loans then they were still humiliating then when he showed the money then the reaction all changed. Even the main person apologised him and asked him how he managed to pay that then he told that his wife managed it and they were shocked how his wife managed so much money from building rooms in the hand to paying loans.
