Business ProfileforMercedes-Benz of Milwaukee North

I brought my car to them. The issue was that it wasnt starting. It was a crank no start. They took my car into diagnose. It charge me for the diagnostic, which is normal. Took them four days to get everything done. They came back with news stating what was wrong with the vehicle I went ahead and paid for a part in labor from the motive of them telling me what was wrong with my car judging from there diagnostic. I eventually got my car back, not even a week three days at BEST. My car would not start. I contacted them letting them know. The issue is still happening that my car is not starting after it being diagnosed was guaranteed that the issue was what they saw yet my car steel was not operating correctly, Ive been proceeded to call and let them know. They asked me to bring in the car. They did another diagnostic and stating it is something else which additionally I would have to pay $2000 more after them wrongfully diagnosing my vehicle with something that possibly was not the issue in the first place , I have not yet spoken with the supervisor my supervisor is avoiding me. Terrible. I will never bring my car back. I am so dissatisfied with my service
