Kilokor motors are ******

I bought a rent to own Audi from them. I payed 20000 deposit upfront and we agreed that i would pay 4000 per month plus 1000 for 5 months to finish the deposit off as it was 25000. I found out the aircon wasnt working, I drove the car for 2 weeks and the engine was damaged, i sent it back to them they first told me that i must pay 23000 to fix the car, after i went there for several days, the agreed to fix it themselves. But i had to wait 3 months for the car to be repaired while i was paying them everymonth i did not have a car, finally it came back at the end of January after about 3 months, it had a funny sound when i was driving i took it because i was very desperate, i drove it for only 2 weeks and the engine got damaged again. They told me i wasnt gonna get my deposit back i gave then their car back. I payed them over 65000 including the deposit but i only drove the car for 4 weeks with 3 months in between. Stay away!!!!!! These people are heartless ******!!!!
