INVERTER SHIPPED UPSIDE DOWN BROKEN

THE COURIER GUY DELIVERED AN INVERTER TO ME COMPLETELY BROKEN AND IN PIECES. IT WAS SHIPPED UPSIDE DOWN SO THAT THE HEAVY BATTERY LEAKED OUT AND TORE OUT OF ITS BRACKETS, THE CASING IS COMPLETELY DENTED AND *****S TORN OUT. THE COURIER GUY IS HOWEVER DENYING ANY WRONG DOING AND REFUSING TO COMPENSATE ME.
