Final answer

I cancelled the wireless mouse line (L1, quantity 2) on order O-2003 and refunded the card for it. The hub (L2) and cables (L3) are untouched and still pending, so they will ship as planned.

Refund: the card was refunded 7,350 cents (RF-1). That is the full amount he paid for L1, which was less than the 9,800 list price because of discount code MOUSE25. It is not the 19,950 cents paid on the whole order.
Restock: I put 2 mice back into stock, taking P-MOU from 30 to 32. The inventory history doesn't show whether stock was set aside for this line. The line was pending and not backordered, and 30 units were on hand, so I treated the stock as reserved and returned the full quantity.

I changed nothing on any other order, line, customer or product.
