Diagnosis

AI agent (anthropic/claude-haiku-5.5)

The buyer was charged $64.00 twice for the same Roaster's Choice box, 18 seconds apart on October 27. Both charges are completed and neither order has shipped, so nothing has gone out yet. If nobody acts, the buyer keeps $128.00 charged for one box and will likely dispute the second charge, which can cost the shop the $64.00 plus a dispute fee.

Refund capture

Agent proposed

The second capture (order 9DA59200AL576183S) duplicates the first for the same cart and the order has not shipped, so returning the extra $64.00 removes the double charge before the buyer disputes it.

Note: Refunding the duplicate $64.00 charge for cart-92468 (Roaster's Choice box). Sorry for the double charge.

Ask the owner

Waiting for you

Agent proposed

Only the owner knows whether the box will ship and whether the buyer should keep the first charge, so this needs confirmation before any money moves.

Note: Both orders for cart-92468 are unshipped. Do you want to keep the first charge (order 6LR58694J58438925) and ship one box, and then approve the refund of the second charge (capture 18F10635SV226950J, $64.00)?
