Bad Service

I bought a KIA cerato 2.0 EX 2015 and started having issues with shuddering and battling to select gears on the car from around 25000 KM the clutch was actually replace about a month or two ago but still having issues with the gears on the car. I sent it back, the next morning they told me I could come and collect my car and all was sorted out. Next morning got in my car and once again battled to select gears. The car was then sent back again and the head mach said he would personally check out my car himself got my car back 2 days later and once again the same thing. I sent the car back yesterday, got a call this afternoon which was suppose to be first thing this morning asking if they could strip the gearbox out again because they THINK it might be the flywheel, but the car could be there a while as they need to do a warrentee claim and they do not have the part in stock so it would be on back order. At this point I have lost total faith in this car and the people looking after it. Take the damn car back and give me another one problem solved as I have given them every opportunity to sort out my car and still nothing. Cherry on the cake, they do not give you a loan car to use in the mean time which is really frustrating, they said they could get me one but I would have to give them a R1700 deposit for what man. Every car I have ever bought I didnt have this issue, as soon as my car had to stay for more than a day they would arrange a car for me. This is really bad form guys. So as I walk or catch a bus to work I have to think to myself that I pay R 6000 a month for a car but I have to do this to get to work great stuff guys. You will never be a top dealer anywhere. When im at work I sometimes have to go out to our other data centres to sort out servers now I have to tell my boss I dont have a car as it is back by KIA. They have had my car more than what I have had it over the past while.
