I PAID FOR THE SERVICE I NEVER RECEIVED!!!

IN MAY 2015 I TOOK MY CAR 2 AUDI WESTRAND 2 HAVE IT DIAGNOSED & 2 GET A QUOTE ON WHATEVER THAT NEEDED ATTENTION & POSSIBLY ACCEPT IT, WHICH I SUBSEQUENTLY DID. AT THE TIME THE ENGINE LIGHT WAS CONSTANTLY ON, IT ALSO HAD SOME OIL LEAKS & WAS ALSO JERKING. SINCE THE CAR WAS DUE FOR SERVICE I ALSO REQUESTED THAT THE SERVICE BE DONE TOGETHER WITH ALL THE REPAIRS THAT WERE 2 BE CARRIED OUT. LATER ON I WAS INFORMED ON 15.06.2015 THAT THE CAR WAS READY 4 COLLECTION & I WENT 2 COLLECT IT. IN LESS THAN A WEEK I NOTICED THAT THE CAR WAS STILL LEAKING OILS & THE HEAD LIGHTS SWITCH ON & OFF WHILE DRIVING, I IMMEDIATELY TOOK IT BACK 2 AUDI WESTRAND. THEY GAVE ME A LOAN CAR WHICH I HAD 2 FIGHT TOOTH & NAIL BEFORE I GOT IT. ON THIS DAY THEY TOLD ME ABOUT MANUFAULT OR WHATEVER IT IS THAT NEEDS TO BE REPLACED & AGAIN THEY WANTED ME 2 PAY FOR THIS BUT I COULDN'T AGREE, I'D JUST PAID THEM 32K 4 ALL ERRORS THEY SAID WAS THE PROBLEM, HOW THEY COULDN'T PICK UP THIS MANUFAULT THING 1ST TIME AROUND IS BEYOND ME. THEY OFFERED 2 TRY & FIX IT 4 FREE. YESTERDAY I WENT 2 COLLECT THE CAR AGAIN AFTER IT WAS DECLARED PERFECT, LAST NIGHT THE ENGINE LIGHT CAME ON ONCE AGAIN. AUDI WESTRAND STILL REFUSES 2 ACCOUNT!
