MERCEDES BENZ COULDN'T BE BOTHERED

I'M THE UNFORTUNATE VICTIM OF A CRIME, IN WHICH MY RIGHT BACK WINDOW / QUARTER GLASS WINDOW OF MY MERC CLC GOT SMASHED. CRIME IS RAMPANT IN OUR COUNTRY HOWEVER, THAT'S THE LEAST OF MY PROBLEMS GIVEN THAT CUSTOMER SERVICE AT MERCEDES BENZ SA IS NON EXISTENT. I WAS INFORMED BY SERVICE PROVIDER PG GLASS THAT MERCEDES DO NOT KEEP STOCK OF THE GLASS & HENCE IT'D HAVE TO BE ORDER FROM GERMANY & DELIVERY LEAD TIME IS APPROX. 4 WEEKS. HORRIFIED! I FEEL IT'S ABSOLUTELY PREPOSTEROUS FOR A BRAND LIKE MERCEDES BENZ TO NOT KEEP STOCK BUT ALSO, EXPECT A CUSTOMER TO BE AT RISK WHILE WAITING FOR SUCH A LENGTHY PERIOD FOR THEM TO SUPPLY. NEVERTHELESS, I WAITED & DROVE MY CAR TO WORK & HOME ONLY DUE TO THE LIMITATION THE WINDOW HAD IMPOSED. A WINDOW ARRIVES 4 WEEKS LATER, TO MY DISMAY THE INCORRECT SIDE WAS ORDERED (LEFT INSTEAD OF RIGHT).DUE TO THIS INCONVENIENCE PROCEEDED TO REQUEST URGENT DELIVERY FROM MERCEDES BENZ SA, HEAD OFFICE CUSTOMER SERVICE DIVISION. MERCEDES BENZ MANAGER LANCE HAS YET TO CONTACT ME BACK. I HAVE BEEN SPEAKING TO AN AGENT LINDY WHO'S NOT A DECISION MAKER AND HENCE IS NOT IN A POSITION TO MAKE THE REQUEST HAPPEN. I'M FRUSTRATED, UNHAPPY AND NEED AN URGENT RESPONSE!
