The chatbot is just an automated animated index into the Help.
You need to talk to Live Chat, staffed by real live human beings, about this.
Get in Touch (all the options, and the best place to start):-
On a screen with big buttons all around, you may find the link you need is under a tiny green arrow, so be vigilant.
Live Chat and Send Us a Message:-
On Live Chat, when you can get onto it, keep your answers short, sweet and prompt, or it will time out on you.
If the person you are talking to doesn’t seem able to understand your issue, ask to be escalated to the next level of help.
<If you can’t access Live Chat and nothing happens, try a different browser from your usual one (Internet Explorer, Edge, Chrome, Firefox, Safari) on which you haven’t disabled pop ups, third party cookies or indeed any cookies, and haven’t set an Ad Blocker, as any or all of these things may prevent the Live Chat window appearing>
