I PAID FOR BRAKE PADS THAT WERE NEVER REPLACED!!!!

IN DEC 2014, I SERVICED MY 2014 RENAULT CLIO AT RENAULT MELROSE. THE REPORT CAME BACK AND SAID THAT MY FRONT BRAKE PADS NEEDED TO BE REPLACED. I AGREED TO HAVE THEM REPLACED AND PAID ALMOST R 1 200. IN JUNE 2015, I SERVICED MY VEHICLE AGAIN AT THE SAME SERVICE CENTRE, REPORT CAME BACK AND SAID BOTH MY FRONT BRAKE PADS AND DISC NEED TO BE REPLACED. THEY NEVER REPLACED MY BRAKE PADS IN DECEMBER. THEY ARE A BUNCH OF ******.
