Very bad service from buying to workshop at Hyundai East Rand Mall

I've bought a Brand New Hyundai i20 2024 Year model in April 2024 at Hyundai East Rand mall. Sometimes in September this year I've notice that the cars "PULLEY" had a Warble I then contacted the dealer where I bought the car 5 Months ago. I was than informed to bring the vehicle in which I took the car to the dealer on the 03 October this year I was than called that same day by my Service advisor "Estée" that the car fixed and I should come and collect the car. on arrival I started the car in front of Estee and the car was still doing the very same thing and she suggested that I booked the car in for the next day which I did. on the following day which was on the 04 October this year I dropped the car off at the dealer again and was told by Estee that they will contact me during this time. so the car was at the dealer for approximate a week without any call or communication from the dealer until I had to go my self and find out what was discovered on the car and what will be the solution to it. so I was than told by the "Workshop Manager" that the Pulley of the Car needs to be replaced so left the car again at the dealer, few days after I was called by the dealer to advise me my car is ready and sorted, everything is 100% on arrival again I started the car again and the very same problem accurse I Feld so hopeless and angry and tired I immediately than went to the Workshop Mangers office too and his exact words was I should not worry the car pulley is 100% it should do the warbling that's how the new i20 were designed. I than took another step to involve Hyundai Head Office where by I was connected with Elizabeth and that was also not a happy client service as I had to call her daily for any updates on the matter and she eventually told me that she has been liaising with the Workshop Manager at the dealer and his reply was that they have replace the pulley and the car is 100%.

I than took the car again to another Dealer on the 28 October 2024 which is "Hyundai Boksburg" I explained to Brain what a bad experience I had with Hyundai East Rand Mall. I must say so far Hyundai Boksburg communication are prompt. I STILL ASK MY SELF HOW CAN A BRAND NEW CAR GIVES YOU SO MUCH PROBLEMS
