Paid name change doesn't like Cdn postal code

Howdy,

I'm paying for a friend to transfer his toons from one server to another, and change the name on one of them.

On the paid character transfer screen, we entered my credit card information four times for the four toons we are / he is moving. No problems at all.

When we tried to change the name on one of the toons though, the name change area doesn't like the Canadian postal code. The form looks exactly the same as the form for paid character transfer, and still asks for a "Zip/Postal Code" - but pops a message that says "Invalid ZIP. Enter in a 5 digit US zip code".

Please help me spend my money. I don't think that's something Blizzard normally has a problem with! :-)

Thanks,

Beebolini
