PREMIUM BRAND BUT LACKING BASIC SERVICE DELIVERY !!!!!

My car was booked into a service at 100 000 km exactly, thinking that the car would still be covered as they say motor plan up to 100 000 in my mind that includes 100 000 and even if it did not REALLY this is called services ?????? For a premium brand I expected more. Then I get told that the gearbox needs a service (NEVER HAPPENED DURING MOTOR PLAN) and get handed the biggest bill ever. To make matter worse I actually reach out to the complaints team and they said they would escalate the matter and get back to me, this coming from the manager LANCE (yes you Lance) 4 days later and nothing. Every time I call they tell me he is in a meeting and will call back.... I am still waiting. Thank you Mercedes Benz for the worst service, you have just lost two costumers for life, but I guess you don't really care do you, as from what I see on this website you never respond.
