bad after sales service

I HAVE A MAHINDRA XUV 300 W6 2022 MODEL. TOWARDS THE BEGINIING OF MARCH 2025 I TOOK MY VEHICLE TO KELSTON MAHINDRA , KOMANI FOR REPAIRS UNDER WARRANTY. THE FRONT PASSENGER WINDOW WAS GIVING PROBLEMS BY JAMMING WHEN CLOSING. THE INFORTAINMENT SYSTEM WAS GIVING PROBLEMS ALSO. WHEN I GOT MY VEHICLE BACK THE WINDOW SEEMED FINE AND THE INFOTAINMENT SYSTEM HAD BEEN REMOVED . I WAS INFORMED THAT IT WOULD BE REPLACED IN ABOUT 10 DAYS. ABOUT 2 WEEKS LATER I WAS TOLD TO BRING MY VEHICLE IN AS THE NEW INFOTAINMENT SYSTEM HAD ARRIVED. I TOOK MY VEHICLE IN AT 07H30 AND AT ABOUT 16H30 I WAS INFORMED THAT IT WAS THE WRONG SYSTEM. ABOUT A WEEK AFTER THAT I WENT BACK TO KELSTON AS A NEW SYSTEM HAD COME. THAT AFTERNOON MY CAR WAS DELIVERED BACK TO MY HOME, BUT WHEN I GOT IN AND STARTED IT THE INFOTAINMENT SYSTEM DID NOT COME ON. I REPORTED THIS TO KELSTON AND TOOK THE VEHICLE BACK THE FOLLOWING DAY, TO BE TOLD THAT IT IS PROBABLY A SOFTWARE PROBLEM BUT IT WOULD HAVE TO FIRST BE REPORTED TO MAHINDRA S.A. UP TO DATE (29-4-2025) STILL NO NEW SYSTEM HAS ARRIVED AND I HAVE EVEN CONTACTED MAHINDRA S.A. AND WAS INFORMED THAT THEY WILL FOLLOW UP AND GET BACK TO ME. GUESS WHAT STILL WAITING FOR THAT FEEDBACK. I WON’T EVER BUY A MAHINDRA AGAIN AND WILL NEVER ADVISE SOMEONE ELSE TO BUY ONE EITHER. **** AFTER SALES SERVICE THAT I HAVE EXPERIENCED AND DON’T KNOW ANYMORE WHO TO CONTACT TO GET THIS PROBLEM SORTED OUT.
