Poor service

Hi. I’m having an issue with Mercedes. When my car give me the service sign 2 weeks ago I called Mercedes to book my car for service. It was Wednesday . They booked the car for Thursday and it was on 700km to drive before service. When I got there the car was on ****m to drive and 100048km. They refused to help me. They said they can’t help me because the mileage of the car is over 100000 by 48. But I told them the car says I still have ****m to drive before service, so what’s that means? They couldn’t answer me. They told me they can’t help even if they see I still have ****m to drive, which means they lie to their customers when they say we must wait for a signor a warning light before you can bring the car to them.

Months ago I had problem with my brake pard and they refused to assist me because there was no warning light. I had to drive my car like that, and it’s very dangerous driving a car in that kind of situation.

Please help me how can I fight this. I’m sitting with the car with no service. Are they wrong or Wright ?

Thanks
