Eshop Order cancelation

I am trying to use a URL to change an order status from pending to cancelled.

I have the World Pay Payment Plug installed ah have got all parts working with the exception of when a customer cancels out of the World Pay payment system.

I have been given this we-remember-submariners.com/index.php?op...eckout&layout=cancel which does redirect the customer back to the site but the order which was created stays in pending state.

I am sure I can pass the order number back from World Pay but is there a URL which will change the order status from pending to Cancelled.

Any suggestions welcome.

I believe that is something that would require customization of the world pay plugin in Eshop. Which is something that can be done. Have you submitted a ticket to Giang to ask about this?
