I recently lost a screw from my Ray Ban sunglasses and tried to fix it myself without luck. So took them into the Sunglass hut inside Macy’s at Stonebriar Mall. The store manager was very helpful. He had to remove part of the old screw, rethread the glasses then insert a new screw all at no charge. Then he straightened and cleaned them. This is the quality of service that goes with a quality product.
