Here’s what consumers have asked with answers from Pro:Direct Soccer staff and previous consumers.
I gave and erased up the order... sorry
This happened to me as well. I simply sent them an email indicating the address, the one I listed as shipping, was the same as my billing address. The address fields call for a House Name, which we don't have in the States, and that seems to be the holdup for transactions from the States to the UK site as there is no house name for us. The UK site won't allow you to continue without entering something in that field and when you do, it doesn't match the address with the credit card company. A simple email explaining such to Pro Direct clears it immediately.
