Another interesting thing happened today when I paid with my wirex.
On the first try it showed me failure in payment. Then I retried it and it went through.
Then I looked at my wirex ledger and the specific amount has been spent 3 times!
I also asked the seller if he got the payment 3 times, but he says he only sees one payment.
So somehow the money for other 2  extra payments disappeared in the system.
I already wrote a ticket.
