You may pay your account online using PayPal.
By using the PayPal payment gateway your payment is made via their secure sites - no card information is passed to me.
Enter your invoice number or name and the amount to pay in the boxes and click the 'Pay Now' button to go to the PayPal site.
On that page either:-
log in to your PayPal account if you have one or click 'Pay with a debit or credit card' if you don't, or don't wish to use it.
