TERRIBLE SERVICE COSTING ME MONEY AND TIME

I TOOK MY CAR FOR SERVICE BEGGINING OF AUGUST , THEY WERE SUPPOSED TO CHECK THE AIRCON ALSO BUT INSTEAD THEY DIDNT AND FOCUSED ON THINGS I NEVER WANTED LIKE BREAKING MY FRONT WINDSCREEN WIPER WHICH THEY NEVER TOLD ME THEY WERE GONNA CHANGE IN THE 1ST PLACE .THE GOOD SERVICE I HAD WHEN BUYING MY CAR IN FEBRUARY MADE ME SO CONFIDENT TO TAKE MY CAR THERE FOR SERVICE EVEN THOUGH I STAY IN PRETORIA PASSING ALL NISSAN DEALERSHIP AROUND. I HAD TO CALL AND FIND OUT IF THE PART I WAS WAITING FOR HAS ARRIVED AFTER THEY TOLD ME THEY WILL CALL ME, I HAVE SPENT SO MUCH MONEY ON THIS AND UPSET WITH THE BAD SERVICE AM GETTING FROM VUSI WORKING AT THE WORKSHOP. I CANT AFFORD BEING WITHOUT MY CAR SINCE IS MY PRIMARY TRANSPORT AND HE INSIST THAT I MUST BRING IT WHILE I TOLD HIM ABOUT MY SITUATION. HOW MUCH MORE OF CAR DRAMA SHOULD A SINGLE MOTHER TAKE FOR HER CAR TO BE FIXED WITH A BIG NAME DEALERSHIP
