Customer Care service where?

I am so disappointed with a Renault right now. I got the car I'm driving in 2021, took it in for service when it reached 15k mileage. The guy who assisted me at Melrose said I should take it back when it reaches 30k mileage. Now the car is almost on 30k and I called in only for the lady to tell me that I will have to pay for the service as Renault terminated my service because I missed it. If you care so much about your customers , how come no one ever called me to say that I'm about to be terminated for service? I even went as far as calling head office the lady told me that unfortunately that is not how it work and it's not their responsibility to remind customers and further told me that if I do not take the car in ASAP if one of the lights go on ,they will terminate my warranty. That service was part of the package and I'm entitled to it. I am very DISAPPOINTED Renault!!!!
