Poor service at KIA SILVERLAKES and KIA SOUTH AFRICA

I bought a KIA SELTOS car at KIA Silverlakes on the 16th of November 2021. On the 24th of June 2022, it started having battery problems. I raised a concern that this car is new, it can't have such problems. They sent someone to boost a battery, Was told stories and we moved on. Yesterday 6 April 2023, I was stuck again on the road because of the same battery problem. When I called their sales person, he told me stories of a 2 year warranty of a battery. The same battery that was giving me problems in 5 months after I had bought the car. OK we argued on the phone until he ganged up the phone. Later yesterday I realise that my car doesn't fold windows when I lock it from the outside. When I check on the net I was told that it could be the disconnection/fuse somewhere in thside the car. I have written emails to KIA SA and on the Twitter and Facebook. They have never responded to any of my messages. Whatever you do, never make a mistake of buying KIA, you'll be on your own, customer service is only on paper but not practiced. I think they select cases to give attention to. I'm one of those who were never taken serious! My lawyers are attending to the matter, but I felt it needs to be shared here as well to warn others. Thanks
