Debt remains debt. Every debt is obligatory for us to charge regardless of her friend or family. But we can not roughly charge friends or family. There are several ways we can do. First sign your debt well. Speak from heart to heart with friends or family who have our same debt. Approach him constantly until he feels bored and scared to meet us. If you have not paid off do not ever stop approaching, if need to sleep at home.
The second can be done by involving third parties, such as family or leaders (community leaders). Ask for their help to mediate you with friends or family who have our debt. This way I've experienced before, and it worked.
Third could by bringing to the police or to the court. this can be done if there is evidence of debt sura or any witnesses. Those are three ways I can offer, hopefully useful.
