Quanzhou quanming engineering construction co., ltd., what should I do if I don't give money or return the second-class constructor certificate?

Yes, you can call the company to discuss it. If you don't give money, go to the Ministry of Construction to report the loss, so it's useless for him to hold your certificate, because you are affiliated with an enterprise and an individual. Many problems can be solved. If the enterprise reaches a non-negotiable result, it will not talk to the enterprise. Go directly to report the loss of the certificate and then declare it in the newspaper.
