Kia South Africa warranty issue

I would like to share the experience that im having with Kia motors Durban branch in Bramfischer. My kia rio 1.2 sedan vehicle is only under 9oooks but already had 3 oil leak incidents from factory..the branch kept on trying to repair and I have been inconvenienced with having to book my vehicle..the 3rd time kia repaired my vehicle but this time damaged my gear box and when I use the vehicle the gear leaver moves on its on on 1st gear ...so I imdiately contacted customer care and they brought in a technician from their head office to have a look at the vehicle that happend last week thursday...then kia keeps quiet and does not give me feed back so this week I have been trying to call the principal dealer at the kia branch but to no avail no answer I left a voice msg and still have not got a call back..so I called the head office and they are surprised that I do not know whats happenening... the service is pathetic.. and I feel I derseve a new vehicle due to the fact that my vehicle is still new and it already had 3 repairs done on the same issue and now on the final repair kia damaged my gear box...I regret buying a kia due to the level of after sales service and the fact that they will just try to repair your vehicle over and over and over again some one needs to make a warranty decision and as per cpa provide proper customer satisfaction..now im left driving a faulty vehicle not knowing when the gear box will give up on me completly.
