What should I do if the subway security machine package is stuck and the security machine manufacturer refuses to pay?

When the subway passed the security check, the security check machine got stuck and broke down. Please contact the subway staff to deal with this problem first. When contacting the staff, you can explain the situation to them, ask them to record the incident and provide corresponding proof materials so that they can be held accountable later. The damage of the security inspection machine is caused by the quality problem of the machine itself. You can find the manufacturer of the security inspection machine to defend your rights. Neither of the above methods can solve the problem. You can protect your rights and interests through legal channels. You can consult a lawyer or relevant legal institutions to understand the ways and specific methods of safeguarding rights.
