Bad service

The service I received from that dealership is so pathetic to say the least. Brought my car in for service and I was told about a 20km drop off. When the car was purchased I was not informed about the 20km radius drop off. Suddenly im told about these! Can this clauses be disclosed when we purchase vehicles so we know if we can purchase at those specific dealers. I have a preference because I purchased the vehicle there and I'm comfortable servicing there .. Jan was adament that I will not be dropped off if it's not within the 20km radius. I'm very disappointed with the service I received.
