I used a credit card to pay, but I didn't go to the merchant's account and I couldn't get a receipt. Will the money be refunded to my card?

Don't mislead the card reader again. I work in unionpay system. If there is no receipt for such questions, as long as there is no problem with the printer and it is not typed, 99% will be returned to the cardholder's card. Either the deduction has been made, or the credit card has been successfully swiped, but it has just been transferred from the issuing bank to the UnionPay system. If there is no receipt, it is unsuccessful. UnionPay will return the money. It is impossible to ask the issuing bank whether it is successful or not. In this case, just call the issuing bank, refuse to pay if there is no receipt, that is, there is no receipt, and then swipe it again. There are too many people who don't understand this now, and too many people are misleading. We often see people arguing about it.
