SAME REPAIR, NO END IN SIGHT

I PURCHASED MY VEHICLE MARCH 2015 WITH 30000KM. SINCE THEN IT HAS BEEN TO HYUNDAI 3 TIMES WITH AN OIL LEAK PROBLEM. I HAVE TO TAKE IT IN FOR THE 4TH TIME WITH THE SAME PROBLEM. IT SEEMS THEY CANT FIX IT AND THERFORE MY CAR SEEMS TO BE A S****. THIS CAN NEVER BE NORMAL. THIS IS THE WORST EVER. CANT SEEM TO GET A PROPER RESPONSE FROM
