Charged for non-operational equipment

I have hired from them before and had good service however on this occasion they rented me a chain saw which refused to start. The backroom guys in the store eventually managed to start it but neither myself nor, importantly, their own manager could start it and I finished up having to pay R230 for the privilege of not using it. Was not prepared to fight over it but stay away from them for anything with a motor - looks like insufficient maintenance or old clapped-out equipment.
