So third avoidable wreck on 9 months. First one mirror struck branch second backed up to commercial door, door came down hit rested on bumper. Zero damage first wreck second just mirror. Third wreck on large incline emergency brake on wasn’t in truck due to electrical issue and truck died so I was putting out triangles and truck slipped gear. Mechanic report stated brake shows lining complete gone and e brake was not working and failed. Truck had all kids of electrical and other issues. Manger said I let it roll back and go in ditch but tellamatics shows the truck was off and the longitude and latitude report shows truck never moved an inch. Panel hearing Monday. Any thoughts or advice
