Hi, and I'm really sorry you had to call in over the digits
I'm bringing this up with our CS manager to see what happened and why that was the case.

I can only l answer in general as to why it might have happened right now. One common issue is that a card is "flagged" for being a purchase outside of a customer's usual buying habits. That's a fraud protection that sometimes happens particularly with overseas orders. A sudden charge appearing in New York from someone who normally shops locally can raise an alert. When that happens, we have to speak with the customer.

Again, I don't know that this is the exact situation here, though it is the most common explanation. But I don't actually work in billing or shipping, so I'm going with what I know from limited experience!
