How do I update as the site are looking for my old card and this is no longer in use as I have dropped it and blocked it?
Apologies for the late reply, but maybe I can still help :)
Have you tried to use an incognito tab, clear the cookies of your browser and use another browser or device?
When this doesn't work, you should try to use another internet connection (e.g. cellular data instead of WiFi).
Have a nice day!
