Unresponsive on issues

I purchased a new Chery Tiggo 4 Pro close to the end of February 2024 at the Century City dealership. On day 1, we found a cut in the front passenger seat. This was fixed. But it seems my issues started there as that was the first time I needed to take the service centre. The car started making a weird sound when it was windy or if you were driving on the highway where enough wind is created. The car was returned to the service centre but they could never replicate the issue. Multiple videos was taken of sound and handed to the sales consultant who sold us the car, Charlene. The car has been to the service centre so many times I’ve lost count. All their attempts to fix this has been unsuccessful (adjusting the door, replacing rubbers, cleaning pads around wheels). I’ve been in contact with Charlene, that handed this matter to the workshop manager, and I’ve stated I need a courtesy car as I cannot keep making these arrangements and the issue is not fixed. Its been more than a week with no further feedback or update. I’m not happy with this service
