It may well be that the shop didn't wait for the thermostat to open and top the circuit up when they replaced the coolant liquid. I would top up the circuit up to the mark you see in the radiator, start the engine, have it run until the thermostat opens (lower hose warm), top up again if necessary. I would then look under the car to see if there is any leak. Then go and drive the car and check the level again.
In the US, or at least on the East Coast, coolant liquid doesn't come ready to pour in the radiator as is the case in Europe and may be in Australia. You have to mix it with water as per the indications at the back of the container.
Also there are a lot of stories about MBs needing specific antifreeze, not the green stuff, otherwise aluminum parts may desintegrate. In doubt, get your antifreeze at a MB dealer or make sure it is MB compatible.
