The POS machine failed to swipe the card, but what happened when I received the debit message?

After the transaction fails, you can use the same card to brush a small sum of money immediately, and maybe you can rush the money back to Poland to apply for frequency drugs; If it is not returned immediately, it may be short payment or long payment. You can go to the issuing bank and tell them that the transaction failed because the payment slip was not signed. It takes about 7~ 15 working days to return the goods.
