very bad service and no ownership

I took my car to Kia Northcliff on the 23rd of September to be fixed 3 things 1.Dashboard lights were not switching off 2.Car had oil leak 3.Gear shift was not smooth after 4 weeks of waiting for the car to be fixed i finally got it back and paid R17k for the service only to realize that the oil is still leaking and the gear's are still not fixed the only thing that was fixed is the lights that were on on the dashboard. Manager later tells me that they dont fix automatic gearbox and he was only trying to assist me and if i want he can refer my car to specialist that deals with automatic gearbox, this story he tells me after taking my R17k and giving me a car thats not fixed.
