Unfair dismissal company opened a case of theft when the cable is still in the building

Delta tactical security in crosby Johannesburg

My hubby was working for this company He did the honor of connecting a heater for their control lady firstly the cable doesn't belong to the company . The company went and opened a case because my hubby went to ccma for unfair dismissal without having warnings or disciplinary hearing. The old man that lives on the premises claims I stole the cable BUT the cable is still on the premises
