Robbing

Hyundai Grahamstown showed me flames ,I bought a new car there in 2021 end of December. I took it to the first service on December 2022 nd I was told is too early I must come back on Jan . I took it back on end of Jan and the car was serviced for 15000 km service. On October 2022 I left the country and parked my car in the house garage, the car is around 17000ks .I sent someone to take it for service of 30 000 and I'm being told that the car is too late for service and I must pay for it ,they even quote me .I'm still not yet back in SA bt I'm coming back soon I wanted my car to be serviced and fresh before I drive it. The car is only on 17000 and I only serviced it once out of three services but now they already want me to pay for it.Firstly the told the person I sent they need a proof that I'm away when I'm about to send them ,they told the person I sent that I will have to pay for the service.
