The pos machine only issued the card voucher, but it didn't arrive at the account and didn't receive the text message.

In this case, it is very likely that there is a transfer order. I suggest you check the balance of your bank card first to make sure it hasn't arrived, and then contact the person who helped you install POS. This situation is very serious and will basically be solved. Let the POS manager cooperate with the reason that the bank can't find, and you will hopefully adopt it.
