Hyundai workshops sloppy, rework same fault twice

Towed H1 to Hyundai Bryanston with clutch pedal on floor. R10,000 clutch replacement had no effect, same fault back after collection. 2nd repair allegedly hydraulic cylinder, even tough they first said release bearing after stripping. Now 40km after collection, clutch not working properly. Dealer principal Philip courteous but no apology and refuses loan vehicle while car goes back for 3rd attempt to fix. Suspicion that clutch never needed replacement. Faulty parts have disappeared. Had similar (3 times re-work) experience with radiator replacement at Hyundai Bedfordview. Service attitude and workmanship not suitable for a commercial vehicle.
