What if someone owes me money and doesn't give it, doesn't answer the phone or send a text message?

So this man, do you want to check whether he borrowed money from other friends? Or have money from relatives and friends you know. It is possible that he has owed a lot of money and may be gambling now. These are all possible. He has no money to pay you back. Did you find him? Just sign an iou. If there is an iou, you can sue him, so the prosecution fee is also very cheap. If you don't have an iou, this may be a little troublesome, so you should take abnormal measures instead of going through legal procedures.
