I received the dunning message, but it has been paid off, and I can't get through when I call back. What should I do?

They sent you a message. I think we should go to that platform first to see if it is really paid off. If it has been paid off, you can ignore him. If they continue to harass, you can choose to call the police directly or blacken them. There are many such scam messages now. You can also set it yourself at ordinary times, that is, set a threshold for those fraudulent harassment messages, so that you won't receive such messages again. I hope I can help you!
