One of the worst service systems in the world. You...

One of the worst service systems in the world. You have to come in and hand over your car document with the key to the receptionist. She will then make you wait for a service advisor who is supposedly going to explain to you the service in detail. You wait for 45 minutes and the advisor will come and just inform you when to pick up the car. I do not understand why you have to wait just to find out when to pickup your vehicle. This can easily be communicated over the phone without wasting people's time. Mercedes service management should visit and learn how Range Rover run their service department.
