Poor Service

I booked in my car for a service on the 8th of Nov 2019. My service plan expires Jan 2020 or 90000KM. My car mileage was 90500KM. They denied to do service and demanded that I pay which did not make sense for me. To my surprise, they took my car back without my consent to an office park - and dumped my keys with the wrong company and no notification to me. Until I started questioning and following up on where is my car. Spent days without my car because of this. This is poor service.
