I lost money sometime ago and I found some legal coins couldn’t be sold for anti-money laundering. This is an unfair clause

When the seller received the payment, he maliciously said that he did not receive the money. He asked the buyer to provide the remittance details before he was willing to ship. The buyer provided the remittance receipt before issuing the currency. It should be that some people did not provide the receipt and maliciously embezzled the money. The delivery is very sweet.
