I have a problem trying to buy coins with VISA, I see "The transaction is not finished". I went to ask my bank and they told me they couldn't help me (if anyone knows why this problem, please tell me).

And now I want to try the "mint" payment method, but the truth is that it is my first time that I see that payment method. I would like to explain to me how it works please. Thank you :) (ah I want to send a ticket but only the "bann appeal" option appears)
