Unprofessional service

I bought KIA December 2024 and my experience with the people has been nothing but disappointing. Got the papers that said 2024 model, then in January to be told that I must change my disc as now the car model is 2025. Even getting the tracker that KIA works with what I nightmare, the lady was just MIA. Then I thought all was well, until on the 15th of September, I received an email from KIA no-reply to say that I missed my service date. I took a day off today to take the car for service, only for them to tell me KIA services declined saying my service is too early. I am appalled at how they do not consider our time, we work and have life to do and no time for such careless mistake.
