Diagnosis

AI agent (anthropic/claude-haiku-5.5)

The customer night-owl-mvr2k1g7695@example.com was charged $64.00 twice for the same cart (cart-39850), 18 seconds apart, on two separate orders. Neither order has shipped, so the customer has been charged $128.00 for one $64.00 box. If nobody acts, the customer will likely see two charges and file a dispute, and PayPal does not treat this as seller-protected.

Refund capture

$64.006K3999595E594764SWaiting for you

Agent proposed

The second capture (order 77D55863AC133030M) duplicates the first for the same cart and has not shipped, so refunding it returns the extra $64.00 to the customer.

Note: Hi, we found a duplicate charge for your Roaster's Choice box and have refunded the second payment of $64.00. You should only have one charge for this order.

Ask the owner

Waiting for you

Agent proposed

Refunds wait for the owner, and the owner should confirm nothing has shipped before the money goes back.

Note: Both orders for cart-39850 are unshipped. Please confirm the box has not been sent, and that you want to keep the first charge (order 23S94959TB6611222) and refund the duplicate (order 77D55863AC133030M). Approve the $64.00 refund to proceed.
