Bad service

When purchasing a vehicle in September 2020, I was informed that service plan for the vehicle has been extended with the new company Liquid Capital, which will kick in when the then service plan expired . In December 2021 I sent the vehicle for 75000km service the first time with the new company "Liquid Capital" I encountered problems right from the start, they told me that my car was overdue, I told them my car has to be in for service at 75000km of which it was at 75000km that time, I was told that the following year my car should be in for service in June 2022, to my surprise when I sent it for service, I was told at the dealership that liquid capital declined my application saying the service plan for my vehicle has expired, I only used their service once I wasn't made aware that my vehicle's service plan will expire so I can make a plan in time. They don't communicate with clients it's like they providing a free service.im fed up with liquid capital.
