I saw today that my virtual card has been blocked, why has it been blocked? i'm excepting a refund on that blocked card, will it be credited in my account?
You should contact their support to ask about the blocked card. It was probably blocked because of the incoming refund. If your virtual card is not fully verified and if the limits are on the lower end of the scale, then the refund might have hit your card's limit which explains the block.
Or, if unverified, the card is probably not allowed to receive refunds.
Or, if you have a Wave Crest virtual card and you are not a resident of their allowed countries, then this should explain the block. This list of countries was recently shrunk and restricted to residents of mostly EU countries (Turkey and Israel included). The rest of the world is excluded.
If you do not live in any of the countries below, then you should contact Wirex's support to ask about your refund.
Andorra, Austria, Bailiwick of Guernsey, Bailiwick of Jersey, Belgium, Bulgaria, Canary Islands, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Gibraltar, Greece, Greenland, Hungary, Iceland, Ireland, Isle of Man, Israel, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, Netherlands, Norway, Poland, Portugal, Romania, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, and the United Kingdom.
