Every month my father has to pay 115000 as interest to different people. Even for some month he has to borrow more money to pay emi and interest. We don’t have regular source of income. Now we are in heavy debt and are unable to pay any further. But my father is a honourable and respected person , if someone show any rude actions toward him then he will not able to cop.
