negligence and bad attitude

ON 2015-10-05 WE TOOK OUR KANGOO IN FOR A SERVICE ON A BOOKING THAT WAS MADE IN ADVANCE. WE WERE TOLD THAT IT WOULD TAKE ABOUT 2 HOURS AND THAT HE COULD WAIT AS WE COME ALL THE WAY FROM MALMESBURY - 42KM. 3 HOURS LATER HE PHONED ME AND SAID THAT HE WAS TOLD THAT HE CAN RATHER GO AS THEY DO NOT KNOW HOW LONG IT IS GOING TO TAKE. I DROVE THERE FROM MALMESBURY TO PICK HIM UP. ALMOST BACK IN MALMESBURY I GOT A CALL TO SAY THE VEHICLE IS READY. I TURNED AROUND AND DROPPED HIM OFF JUST TO BE TOLD WE CAN TAKE THE VEHICLE, BUT HAVE TO HAVE IT BACK THE NEXT MORNING AS THEY NEED TO ORDER FILTERS THEY DON'T HAVE. THE NEXT DAY HE HAD TO TAKE THE VEHICLE BACK AND WASTED ANOTHER 2 HOURS! ON 2015-12-31 I HAD TO BOOK A SERVICE WITH THE SAME DEALERSHIP AGAIN AS THEY WERE THE ONLY ONE TO HAVE AN OPENING. ONLY AN OILCHANGE LATER I GOT STUCK IN 40DEGREES HEAT NEXT TO THE ROAD FOR 4 HOURS WITH NO OIL IN THE VEHICLE AS THE SUMPPLUG WERE NOT FASTENED. SPEAKING TO THE MANAGER/OWNER I WERE TOLD ITS UNFORTUNATE BUT THEY ARE CLOSED FOR NEW YEARS AND THEY CAN ONLY ATTEND TO IT ON MONDAY THE 4TH OF JAN. ONLY AFTER THREATS, EXCUSES AND BAD ATTITUDE ON HIS SIDE I WERE ASSISTED WITH A LOAN CAR AFTER BEING TOWED.
