sub par quality

I purchased a Brand new VW T-Cross from VW in Centurion (Pretoria) in July 2022, about a month later, My wife noticed that the front tweeters were distorting and we took the car back to VW, we were then informed that they could not find the issue.

another month went past and the problem persisted, We took the vehicle back again and i played the music from my phone (not at full volume) and the technician heard the cracking of the tweeters, That afternoon we were informed that the problem was not resolved.

I took the car back again about a month ago and took my wife with, we asked the services manager to come with us to the vehicle to hear the noise that a brand new VW makes when you play music. He heard it and confirmed that the tweeters were making a noise, now i get a call from VW Centurion stating that its a characteristic of the vehicle. "We are unable to escalate the "fault" because it is not a fault but the characteristics/DNA of the vehicle"

Do you mean to tell me that VW intentionally puts in sub par quality speakers?

This is a brand new vehicle and all i want is the quality that VW promises.
