My dealer lied about my new car's service history - what action can I take?

I brought a Mercedes-Benz on 25 February 2017 and was told that the car just had a service done. Two weeks later, when I visited Mercedes-Benz there was nothing showing on their system. I've emailed the dealer a few times to chase up service details but have had no joy. I'd like to take more action. What do I need to do?
If the dealer who sold you the car was not an official Mercedes-Benz dealer then he wouldn't have access to MB's central computer and could not enter the service on it. If he is an official MB dealer then he is liable for whatever cost of the service that was due.
