Poor Service and Neglecting their Customers

We bought a pre-owned KIA RIO at Randburg dealership on the 29th June 2015 assisted by Lloyd Kgobane, on the clock it was almost 60 000 and it has warranty . we drove the car until started to lose power and unstable rev count a month before the 19/OCT/ 2015 when we took it back to KIA Randburg for diagnosis, in fact I called Lloyd prior that, he thought maybe is the clutch balance since is our first time driving KIA.till now the car is just parked and not been attended as they will forever tell you they waiting for a part and they dont give out courtesy car even thou they inconvinienced us instead they say KIA SA authourised us a loan car from Europe a Car where we need to pay refundable 1500.00 which we dont have, they took back their car which i fought for them to give us been told they need to give it to other customers even now we out of the car struggling with kids.the senior manager told us even if we go to KIA SA its pointless as they will refer us back to him. this is really frustrating as we are paying every month and they had shown no remorse at all and we wont feel safe in it due to even if they fix it due to attitude we received from them.
