What is the customer service phone number of Li Yun Auto Finance? I have something at home. What will happen if I am overdue for a few days?

This Li Yun auto finance company is a fraud company. A while ago, I said that their system was upgraded and there was a phenomenon of repeated deduction. I want my money back. Now the company has lost contact and only called its partner Bank of Wan Xin, but no one refused. I feel really cheated. I want to defend rights, but I don't know which department to go to. Thank you very much.
