OVERCHARGED SERVICE COST COMPARE TO COUNTERPARTS

MY VEHICLE WAS BOOKED FOR THE 1ST TIME WITH BARONS CLAREMONT FOR MY 90K KM SERVICE. UPON CHECKING TOGETHER WITH THE CHECK-IN CONSULTANT WE ONLY FOUND AN EXISTING SC****. I NOTIFIED THEM OF A FAULTY CHARGER INPUT. I WAS CHARGED R1800 MORE THAN MY PREVIOUS SERVICE FROM BARONS STELLENBOSCH, AND NOTHING EXTRA WAS DONE. UPON RETURN OF MY VEHICLE, MY CHARGER INPUT WAS NOT WORKING AT ALL ANYMORE, I HAD TO BE INCONVENIENCED BY RETURNING WITH THE CAR TO REPLACE A FUSE. I NOTICE THAT THEY PUT ON MY INVOICE THAT MY WIPER COVER IS MISSING, THOUGH WAS THERE WHEN BOOKED IN, AS NOR CONSULTANT OR ME FOUND IT TO BE MISSING. UPON COMPLAINT TO THEM, THEY ADVISE ME ITS ONLY R30. PRINCIPLE OF THE MATTER, IT WAS THERE WHEN CHECKED IN. TELEPHONICALLY THAABIT AGREED THEY WILL REPLACE, OUR WORK DRIVER TOOK MY CAR BACL. THEY REFUSE TO REPLACE, AS IT IS ONLY R30!!! IN 7YRS THIS WAS THE MOST I EVER PAID FOR A SERVICE WITH THEFT OF A SMALL ITEM OFF MY CAR, WHICH WAS THERE WHEN CHECKED IN.
