2009 Nissan Murano wheels problems

Damp patches appeared on the original alu rim 20'. It happened app. 3 months after using my new car. I have reported this fact to service during maintenance, but I was brushed off (it was my filling). Additionally the middle holes have sharp marks after rotating and balance in dealer service. I want to highlight that all works with wheels and tires have been discovered in service. I have reported this fact too, but without effect.

My front brakes are squeaky. Even after having my brakes regularly serviced with pads and rotors the brakes still squeak. Their have also been times when I stepped on the brake but the car did not slow down as expected. I had to pump the brakes to re-engage them. Once this caused me to roll into an intersection which luckily no other cars were near me. Now my front left wheel has started making loud swooshing and screeching noises. The faster I drive the louder the noise gets.
