Staff member cant follow instructions on how to do a software update on infortainment software on a vehicle

My experience at the Kia Cape Town, was very poor. The service advisor by the of Ricardo Meyer, would pretend to know what he is doing when clearly he does not what took me about 20 minutes they couldn't even do in 3 weeks by updating my infortainment system software on my Kia Seltos. I was told only what I wanted to hear not what I was supposed to hear. Like I always say if you dont know what you are doing go and seek advice from people do not over promise what is not in scope of your work. Long story short, I followed a simple instruction to update my vehicle what not even a service advisor could do. It goes to show that its either nobody reads with understanding or just cant do simple task. Kia motors I hope that when you employ people that they actually know what they are doing and not pretending to because my experience at your branch really was putrid and needs major work.
