Miss leading information, lies, unfair treatment

In June 2018 I was told BMW is running a campaign on 2016 model mini coopers, motor plan is extended to 100 000 kms or 5 years.

13 Sep 2018 I brought my car for service at 81 000 kms and it was serviced under the mortor plan. I was not charged anything and they did not say anything about an expired motor plan.

24 September 2018 car breaks down, gets towed to the dealership. On the 25th I am told the car is out of motor plan. But how come when i was told the motor plan was extended to 100 000 kms? Why was it serviced free at 81 000 Kms two weeks ago if it was out of motor plan?

They refuse to give me a car while they "investigating the matter". I am not given turn around time as to when will the investigation be done.

What a way to take care of a customer....I'm so disappointed!
