I, too, have been a victim of fraudulent Mercedes Tele-Aid charges. I returned my GL 450 in 2010. Tele Aid ceased charging then and then started again in 2014 for no reason. I haven't owned a Mercedes in 7 years. Mercedes Manhattan, specifically the general manager and his department, have been no help whatsoever. A complete difference from the way they treat you when you are driving the car off the lot. I am pursuing this with American Express and in court. I will never rent, buy or lease another Mercedes again.
