Hello, I have moved to the united states from Australia and I am unable to change my billing address. I need to change it to the USA because otherwise it will not let me enter my US credit card information. I do not want to be charged for currency conversion. Also my US credit card may be blocked if it is getting a charge in Australian dollars. Surely this should be a simple edit. I no longer have an Australian bank account or card. can someone please help me with this. Kind regards, Phil pja.arnold@gmail.com
