A few months ago, I had an accident with an elderly man and my husband's car was damaged. My husband gave him 20 dinars on the condition that he would take the remaining amount of about 150 when the financial situation improves. Days passed, I divorced my husband, and my financial situation improved. I called my ex-husband and asked him for the man's number, but he told me: I will not give it to you as long as it remains your debt. What should I do? I don't know anything about this man?
