1.A uses a credit card to buy something from B on Taobao and pays 100 yuan. Is the actual amount B received in his account 99 yuan? No. What B received was 100

2. Then A applied for a refund, and B agreed. So if this model (99 or 100 yuan?) has not been shipped yet, you will get a refund of 100. If it is shipped, it depends on whether you have a quality problem or if you return it for no reason. The postage may be deducted and you can apply for a refund. The postage is less and you can apply. 100 off postage

3. Should the refund be refunded to A’s credit card or to A’s Alipay account? When you choose the "Credit Card Payment" channel for payment, the money will be refunded to the credit card within 2-10 working days; if you choose the "Online Banking Payment" channel to pay with a credit card, the money will be refunded to Alipay

4. If the money is refunded to Alipay, can I withdraw it directly? Or can it only be refunded to the credit card? If the refund to the credit card fails, it will be refunded to Alipay. You can withdraw cash, but mentioning the credit card is not supported
