500 yuan was cheated by residential property security. Is the property responsible?

Responsible. Owners who have been cheated by security guards can complain to the property company and defend their rights. As the management of the community, the property management company should supervise and manage the service quality, employee behavior and security behavior in the community. If the owner finds security violations or fraud, he can complain to the property company and ask the property company to deal with and compensate the security.
