Angry and Dissapointed that they are not even traying to help me, they dont care.

I'm very disappointed and angry at Kia Vereeniging their Service and Treatment Horrible, I took My SPORTAGE 4x4 AUTO S/R to them for service in December I paid R 2771 and I had asked them to check all other things that needed to be replaced because I don't want to be stuck on the road because as a woman when something like that happen you never know what to do, they checked and gave me a Quote on all those things and I paid + or - R 25000 for everything. I was relieved that at least My car if fixed and wont have to worry anymore, they replaced the Oil Pump , Water Pump , coolant O -ring and other things. they were the last people to work on the Engen they gave me 1 year warranty so now the car started giving me problems and Told me the ENGINE MOUNTING BROKE ON FRONT TIMING COVER and they OIL PUMP WAS REPLACED IN DECEMBER IN their WORKSHOP so I thought they will fix the car without any problems to my surprise they are telling me I need to pay R 12 182.40 to fix the car , I spoke to the workshop manager thinking he will understand and help me but he was not interested and Johann Van Zyl also told me that its not their fault , I couldn't believe it I'm disappointed on how they treat their customers, I called Kia Customer Care the guy I spoke to also told me they couldn't have seen that that thing will break. I'm stressed and frustrated because I now don't have a car to travel to work, the car is with them they waiting for me to make a payment, I don't have money I really don't know what I'm going to do.
