BRAKE HELP

My brakes make a horrible a screeching noise with light pressure on the brake. They’ve been inspected several times and I ‘m told my brakes are fine. I’m told the thickness of the brake pads is fine. They’ve blown off “dust” which didn’t improve anything. I’m told they can cut the rotor but you can only get one cut from a rotor. I can have new brakes installed but if I’m told my brakes are fine…why would I have new ones put on? I’m at a loss on how to remedy this situation. This is a new vehicle. Brake noise started at 8,000 miles. It’s a 2009 JEEP Grand Cherokee.
