Don't sell contraband. If the customer has a problem, deal with it immediately. If you can get a refund, don't blindly refund it immediately. Otherwise, the loss of waiting to close the store will be even greater. Two stores can use the same card, but they can only withdraw a small amount, and then withdraw it after settlement. Don't withdraw a lot at once, in case the cardholder has too much money and is unstable. Delete the card immediately after the withdrawal settlement. Delete the card in the buyer's backstage. At least I have feedback from customers that everything that has not been deleted has been blocked, and there is nothing wrong with deleting it, but there are also feedback from customers that what has been deleted will also be blocked. This matter has not been verified. However, it is better to delete it to minimize the risk. Step 1: Bind the card, enter the account password to log in the account, enter the seller's background page, and select the bank account. After selecting a bank account, the verification page will pop up. At this time, you need to enter the password of the login account, select Add Bank Account after verification, and enter the Thai name and Thai ID number after entering the next step.
