I've lost access to my email address, so I can't get my one-time code.

Without access to the email access is unlikely: https://help.dropbox.com/account-access/lost-email-access

If you cannot follow whats in there you need to contact support via www.dropbox.com/support while not logged in anywhere - even to here so consider an incognito window instead. 

Thanks I’ll give it a go 

Unfortunately non of that worked and seems I can’t get hold of a a one for help 

jimi, before contacting support, can you double check for any other linked devices you may still have? The one-time code can be found in their notifications, in some cases.

I tried all of that but unfortunately no luck

Can we log a ticket for you then, jimi? We can see if there’s another option this way.

The email address we can contact you at is the one you see here.

Nancyhi yes it is , it’s not the account I’m having issue with, but yes please your help would be amazing 

You’re all set, jimi! Please reply to my email, when possible.
