What is the best way to be free from threat calls from financiers?

My friend got loan from a financier for his daughter’s marriage. He promised to pay the monthly interest after he gets salary every month. All on a sudden there was loss in his company and employees were laid off. He didn’t pay the interest for 3 months. The Financier is repeatedly giving threat calls. He is confused. He has started a small business now with a small investment. Any help?
