Bad expirience

I had a very bad expirience with Hyndai Ballito i had an issue with my car window from last year 23/05/2024 they said they fixed it however its only worked for couple of weeks and did same thing again went back again on 23/07/2024 they lubricated the window so they say, same issue again went back i logged the same issue for the 3rd time they did the same thing on 23/01/2025 lubricated the window went back again for the 4th time with my window covered with plastics because it was raining the whole night i could not close the window where they decided they need to get 1 part for me this was so inconvinience my point is Hyndai Balito delays the process because they want to benefit themselves they dont care about customers as much as this was paid under warranty i feel like it was unfairly charged and they did this on purpose i want to know how on earth does this happen ??????? Can someone intervene on this matter i am not happy at all
