Wholesale lots are not a returns program. Changing your mind is not a claim, and liquidation lots are final-sale purchases.
There is no return flow. A successful claim is settled as a per-line partial refund from the held funds, and you keep the goods.
Closo Direct is different
Closo Direct is the other Closo checkout, where independent resellers sell single items from their own storefronts. Each Closo Direct shop sets its own change-of-mind policy, shown on the listing and on the payment screen before you pay. If a shop has not stated one, you may return an unused item within 30 days of delivery.
