I was cheated by my old classmates. I know his mobile phone number, but I don't answer the phone and text messages. How to retaliate?

Do you often cheat? If it is not much, forget it. If you have a little money to see a person clearly, you won't see him again. Such people are not worthy of being friends. If there are many, there is no hurry now. It's never too late for a gentleman to take revenge for ten years. You have to use your head. If it's a man, it's easy to know his q ... you know, then ask him out and meet again. Are you still afraid of not catching him? What if you don't have to show mercy when you catch someone?
