2000 Pontiac Bonneville 3800 squeak or chirp in the brakes

2000 Pontiac Bonneville 3800 mileage: 60,000. Four days ago I had the rotors turned and brake pads replaced on the front and the rotors replaced on the rear. I noticed a major squeak or chirp in the brakes when I applied the brake the squeal or chirp would go away. Also, when I turned to the left the noise would go away. If I drive straight or turn to the right it is a loud squeal or chirp chirp chirp chirp chirp. I also hear something rubbing at very low speeds. I called the place that did the brake job and they said the new rotors needed to seat themselves and that I should drive it for awhile.
