Disappointment

In 2020 I bought a Kia Picanto at The Auto Warehouse. With in the first day of having the car at home, i noticed an oil leak and the car smoked alot. They fixed it after we told them that it was ********* what they did to roadworthy a car with an oil leak. When I eventually got the car back after all the repairs, I thought the nightmare was over but then the next problem started. The car started making a very loud ratteling sound. Another mechanic checked out the car only to find a lot of *****s, etc. which was lose. I then took the car back to The Auto Warehouse. They took the car in for repair but when I went to go pick up the car, the sound was still there. Now they refuse to help any further even though it is still within the six months after I bought the car. I am very disappointed in their service and I wouldn't recommend anyone else doing business with them.
