TERRIBLE SERVICE AND LIES FROM S2 CAR SALES

I BOUGHT THE CAR CASH ON THE 08 APRIL 2023, ON THE 14 I TOOK IT TO THE MECHANIC FOR THE INPECTION, HE FOUND OUT THAT THE CAR IS MIXING WATER AND OIL. I CALLED THE DEALER AND THEY TOOK IT. TO DATE THE CAR IS STILL NOT FIX AT ALL. EVERYTIME THEY KEEP ON TELLING ME STORIES ABOUT THE MECHANIC. MY CONCERN IS THEY TOOK MY MONEY AND THE CAR. THEIR SERVICE IS SO TERRIBLE. ALL I WANT IS MY MONEY BACK NOTHING MORE. I ADVISE PEOPLE NOT TO BUY CARS FROM THIS COMPANY, THEY ARE BIG ****MERS
