Service Fee For Nothing!

I'm very disappointed with your services. I've been paying a Service Fee for my car with Liquid Capital and have been doing this since I've purchased the vehicle. All my payments are currently up to date and accounted for. My 75000 km service was an issue, but I managed to get it done. I booked my car in for my 90000km service today, but have to take the car back now as liquid capital doesn't want to authorize the service, despite the car being within 15000km since its last service. The car was hardly used as i worked at home during Covid and the mileage was only 10000km over the 75000km services mileage when it was the due date for the service in January, why would i need a service every 10000km? I'm really disappointed that I have to pay this monthly fee, only for authorization to get rejected. I want my money back please or for this issue to be resolved.
