KIA MOTORS TERRIBLE AFTERSALES SERVICE

I believe that once you purchase a new car from Kia you become non existent to them. I have been trying for the last 6 months to sort out a towbar on my 2017 Sportage. I bought the car in Centurion but take it for services to Boksburg. When I asked Boksburg to sort out the towbar, they told me to take it to the fitter of the towbar. I told them I purchased the car with the towbar. But was told they won't touch it as they belong to a different group than Centurion. WHO CARES???? I am the customer!!! So I called KIA South Africa and was told that they would look into it and get back to me. That was a couple of weeks ago. NOTHING! I went online to KIA South Africa and sent my complaint to them. On 29 January 2020 they acknowlegeded my complaint and will revert back to me. NOTHING!!!!! KIA YOUR AFTER SALES SERVICE SUCKS!!!! And this is NOT the first time I have been treated this way by them. DO NOT BUY A KIA BECAUSE THEN YOU ARE ON YOUR OWN!!!!!!!
