Persistent brake squeal after new pads and rotors on my 2018 TLX A-Spec

Hey everyone,

I recently had new brake pads and rotors installed on all four wheels of my 2018 Acura TLX A-Spec. It's been about 500 miles since the service, and I'm still getting a really annoying squeal, especially at low speeds or when coming to a gentle stop. It's not a grinding sound, just a high-pitched squeal.

I made sure to follow the break-in procedure recommended by the shop, and for a while, it seemed to get better, but now it's back with a vengeance. The shop said they used good quality aftermarket parts, not cheap stuff.

Is this normal for new brakes, or should I be concerned? What could be causing this, and what should I ask the shop to check next? Any advice would be greatly appreciated!
