Diagnosis

AI agent (anthropic/claude-haiku-5.5)

The shop refunded $20.00 twice on the same $80.00 payment for the espresso sampler order, two seconds apart, so $40.00 has gone back to the buyer. The two refunds are 49H200786E503940C and 9LY672056T313191W; the second looks like an accidental repeat, not a second decision. Nothing can be undone automatically: the extra $20.00 is already gone from the shop's PayPal balance, and the order is still marked unshipped, so the shop needs to decide what the buyer should keep.

Decisions

Ask the owner

Waiting for you

Agent proposed

Only the owner knows whether the buyer should keep the extra $20 or whether the order will ship, and refunds cannot be reversed by Nightshift.

Note: Two $20.00 refunds (49H200786E503940C and 9LY672056T313191W) went out 2 seconds apart on order 8G9687840C628481K, so the buyer has received $40.00 of an $80.00 order. Do you want the buyer to keep the $40.00 (and then mark this resolved), or should we ask
