Eurostar Business Premier Refund
 

When you ask for a refund on Eurostar business premier from London to Paris does it get credited back on my US credit card or does it show up as a credit to be used at a later date?

My whole trip might be in jeopardy and hence the question with the refund (with no known future dates of going to Europe again)

FYI - I tweeted at them on twitter and they responded that the refund would be on the credit card.
