Last July, I cashed in my friend's POS machine with four credit cards. The next day, my friend said that the POS machine was frozen by UnionPay. I have paid off the money owed to the bank by four credit cards. First of all, freezing funds does not mean confiscating funds, so don't worry too much. In this case, your friend needs to contact the corresponding acquiring institution in time, admit his fault and bear the corresponding punishment, then the frozen funds can apply for normal collection. Generally speaking, the acquirer will freeze the funds for no more than 45 days, and it will definitely be lenient to take the initiative to admit mistakes. As for your funds, it has nothing to do with POS being blocked. You have a debt relationship with your friend. All you have to do is stare at your friends and ask for money.
