I bought a voucher for 30 euro for adCenter. I loaded the voucher in your account, indicated that everything was fine, but the payment / balance shows me 0.00 Euro. Why give me 0.00 euro balance?
by default bing will show 0 balance, which means you don't have amount to pay. just go to your account/billing, choose an account, and see the transaction history. you should see somthing like "30 Euro voucher successfully applied to your account"
Normal is showing 0.00, when they start clicking anger rising, and when you get your $ 30 coupon was over
