After they have got my money they told me:

We’re sorry to inform you that it appears we will not be able to assist you in your transaction. As a crypto exchange, we have to follow strict legal requirements for every transaction we process.
Unfortunately, occasionally this means we are not able to verify customers due to these restrictions. Due to legal constraints, we are not able to give you any more information at this time.
Kindly wait for 1 to 5  business days for bank confirmation after we process the refund. We will refund your payment once it is cleared in our account."
Probably BANXA is fraud and I have to go to police
