Bad service KIA Motors Somerset West, bad communication and no guarantee given so far. - Consumer Complaint for KIA MOTORS - HEAD OFFICE (Complaints)

I bought a brand-new KIA Sportage 4,5 years ago at KIA Motors Somerset West. It is still under guarantee. The service has never been good, but it turned for the worst recently. Although I have a problem in which there is no discussion with the dealer that it should be repaired under guarantee, nothing is happening. Telephone calls are not answered most of the time and if I get contact, I am told that I will be called back with a status update. It is a problem that was mentioned with my last service on 11th February this year. After many complaints I got in contact with the dealer principal, who guaranteed me that he would personally see that the problem was solved soon and that within a couple of days I would hear how the problem would be solved. After sending again proof of the problem on WhatsApp the same day as requested, I noticed that the WhatsApp was never opened. A telephone call I made a week later to inform the status was answered and I was told that I would get an update within an hour. This is more than a week ago. Phone calls are not answered anymore and no reactions to voice mails. I intended to buy a new Kia Sportage 4-wheel drive beginning of next year, but due to the service I received and receive, it will not be a KIA.
