Shutter on clutch - Consumer Complaint for KIA MOTORS - HEAD OFFICE (Complaints)

Clutch was replaced by kia Stikland. Still have shutter on clutch. Took car to Tableview branch. They say clutch wasn't fitted properly. Had car there 3times by Stikland. They say it's engine labouring. Car also cuts out. Stikland says it's the AC that causes it. Tableview says it's the throttle needs to be replaced. Now Stikland expects Tableview to fix clutch which they replaced. I can't keep on taking car back. My work requires that I must have my own transport.
