Here is the follow up email.
"Unfortunately, we don't have the ability to change a shipping address once an order has been placed due to security reasons. If the current shipping address for your order is accessible to you, we recommend leaving it as is and receiving your package there.
If that won't work for you, we can instead intercept this order immediately with your consent. You are welcome to update your shipping address in your Google Wallet account and place a new order.
If you'd like for us to intercept your order, please reply with a message containing "I Consent"."
Now I get to call back and ask what "intercept" means. Great.
