Not honoring service plan

I bought my car October 2023 and took my car in for its first service now end of May. I was informed by Liquid Capital that I should have brought it in a year from purchase and my first service will not covered by my service plan. This is ridiculous. You take out a service plan so your car can be serviced when you can book it in. What happens to all the premiums I paid and not getting what I paid for? Also it will seem that I am not diligent with taking care of my car as when I get my car service in October, that I didn't take it in for it's first service. This is unacceptable!
