Dealerships don't always pay due care and attention to servicing work and it's possible that they didn't fully replenish the oil when they did the service prior to you collecting the car. You say you didn't check the level at the time and presumed it would be full (not unreasonable). The mechanic saying now that oil has been lost isn't surprising - he/she won't want to admit to not properly filling the engine in the first place. It's just possible that there isn't any fault.
You need to eliminate this possibility, so why not top up the engine oil to the full mark now and keep a close eye on it? You need to be certain that it is actually losing oil, and how much, before remedial action can be considered. I would only trust my own measurements, not the dealership's mechanic, who might be making assumptions.
