If a payment fails or you dispute a payment, your account will be blocked until you settle the debt.
To pay the outstanding balance you can pay through a direct payment from your bank account. It may take 5-7 days for the payment to clear. You can also pay by credit card, which will be faster, but please note there is a 3% processing fee.
Once you have settled the debt, your account will open automatically and you'll be able to place an order.
