2015 MITSUBISHI MIRAGE- CLUTCHY PROBLEMS ?

I HAVE A 2015 MITSHUBISHI MIRAGE- BOUGHT AT 10200 KMS ON THE CLOCK AND ON THE 13-01-2016 I CALLED STUCKY MOTORS/MITSUBISHI IN NEWCASTLE COMPLAINING THERE IS A SHUDDER WHEN I TAKE OF ON NO.1 GEAR AND FURTHER MORE I HAVE GEAR PROBLEMS. EVERYTIME I COMPLAINED I WAS TOLD THAT THE SERVICE DPT WILL CALL MITSUBISHI AND SORT IT OUT AND GET FEEDBACK AND LET ME KNOW. UTTER TRASH I WAS THE ONE WHO HAD TO CONSTANTLY CALL BACK TO FIND OUT WHAT THE F/BACK WAS AND FURTHER MORE THE ARROGANCE OF ONE OF THE STAFF: \SO WHAT YOU DID NOT BUY THE VEHICLE FROM US\" IF THAT IS THE ATTITUDE OF MITSUBISHI THEN I NEED TO TELL PROSPECTIVE CUSTOMERS DO NOT WASTE YOUR TIME LOOKING FOR A BRAND OF MITSUBISHI.... I HAVE CALLED THE DEALERSHIP MORE THAN 10 TIMES GETTING ONLY...\" I WILL CALL HEAD OFFICE AND LET THEM AND I WILL GET BACK TO U ' ...GARBAGE ... I WOULD HAVE TO CALL AGAIN BECAUSE THERE IS ABSOLUTELY NO PROFESSIONAL ETIQUETTE AT MITSUBISHI AT ALL!!!.... I EVEN COMPLAINED TO RECEPTION OF THE POOR CUSTOMER SERVICE FROM THE DEALERSHIP. I SPOKE TO GENTLEMAN AT SERVICE AND TOLD HIM IT SEEMS LIKE I AM NOT BEING TAKEN SERIOUSLY BECAUSE THE SHUDDER IS GETTING WORSE AND I HAVE DIFFICULTY CHANGING GEARS....."
