Hyundai oudtshoorn

So I took my Hyundai I 10 to Hyundai to get my car fix for the tps sensor coz it was acting up. They worked for a month and a half on my car. Then they charge you with fixing stuff that was not even the problem. Then they worked on my gearbox putting in a new clutch kit. When I got home there where just gearbox oil everywhere. Took it back they fix the oil. They say they hurt one of the seals when they put it in and told me I have to pay for the seals. So I got my car back. And it was just a mes the car was still jerking and the release bearing is shot. They did not fix the gearbox like they was sepose to. They just messed up my car so I took it to kobus who is working private from home. He worked for many years for Hyundai and he fix my car. Stay away. They will only cost you money and a car that's not fix
