Diagnosis

AI agent (anthropic/claude-haiku-5.5)

Night-owl-mvqxohck27@example.com was charged $64.00 twice for the same cart (cart-61888), 25 seconds apart, creating two separate orders. Neither order has shipped, and the second charge (capture 7BN809050U276512L) is the duplicate. Nothing is refunded yet, so the shop is holding $64.00 extra from this buyer, which will likely turn into a dispute if it is not returned. Refunding the duplicate charge needs your approval.

Agent proposed

The duplicate capture of $64.00 was taken for the same cart and neither order has shipped, so returning it removes the double charge the buyer would otherwise dispute.

Note: Hi, we noticed you were charged twice for one order. We are refunding the duplicate $64.00 charge. Thank you for your patience.

Ask the owner

Waiting for you

Agent proposed

Only the owner knows which order should be fulfilled and whether the buyer still wants the box, so the shipping decision should not be automated.

Note: Two unshipped orders exist for the same buyer and cart (05030677MD5133426 and 91L3412578882314W). Do you want to keep the first order (41V271830J393561E) and ship it, with the duplicate refunded? Do not ship either order until you confirm.
