Thanks for the clarification.
How did you receive the original cards? Personally? While in the US? Have they ever been used in the US?
I had a debit card that had never seen the outside of my wallet get blocked by my bank when a string of charges popped up from Vietnam. Although I was a frequent visitor there, this card had never seen the light of day anywhere. The first three charges were small, and the bank explained these were 'test' transaction by the fraudsters to verify the validity. They stopped the nonsense on the fourth, much larger transaction. Took a few weeks for the affidavit of use to get to them, but they unlocked the card as soon as I contacted them and verbally verified it wasn't me and all the charges were removed.
