Same here. I have a business debit card (bad idea, I know) that I wasn't actually able to complete a purchase with due to Woo being a UK company. That didn't stop the card number theft, though, I had over $3k of fraudulent charges before the bank shut the card down. Spent all morning filling out dispute forms. Good news is I shouldn't be liable for any of it. Charges were from all over the US.

Bad news for Woo, issues like this cost a LOT of money to resolve. They better own up to it soon, this will be a major blow to their reputation if they don't.
