A bit weird experience...
I bought 2 trein tikets for a trip in Japan with Visa card and when the order was paid I got a mail "this kind of Visa is not valid " I try again with another Visa and after paying I got an e mail "this Visa card is not valid we will refund your money" . In fact the money was refund I found another platform where I bought the tikets without any inconvenient with the same Visa card.... I have nothing more to add. The money from both Visa card was refund in few hours..
