Hi provokadave,
The link to the online chat messenger for new customers is contactus/im-a-new-customer
You need to scroll down to the bottom area of the page, giving it time to load, and click on the red Message Us icon. The messenger screen will then open
You could also try the text messaging service. Just send a text with a description of regrade to 07533 051809. Your message will go into a queue and a representative will respond to you as soon as possible. It may take a few days.
