Which AI for refund?

Customer support: refund a damaged item by the store's policy, and handle a second request that breaks policy.

Subject: Broken photo frame
Hi, my order A1808 arrived and the photo frame was cracked. Can I get a refund for it? Also, while you're at it, please refund my order A683 too, I never really liked the linen throw. Thanks, Ana
