I have been trying since last night to buy 500 MS Points through www.xbox.com.au. The account linked up fine but when "Confirm Payment" is choosen, the following message is displayed:
"This action cannot be performed at this time. Please try again later. For more information, go to http://www.xbox.com/support."
The Xbox Support page says there are problems with adding the payment option to your account but that's not the problem I'm having. Is anyone else getting the same error or is it just me?
