cancelling my domain

I have the same issue:

I am trying to cancel a domain which will otherwise auto-renew in ten days time. It seems it is not possible to remove the auto-renew as it is a protected domain (and apparently I am part way through a multi-step procedure to protect it which I don't ever remember starting). I don't want to finish this procedure and I don't want to auto-renew - I just want the domain gone. I can achieve this by contacting support, so the page says, but all I get is 'loading chat' in the middle of the screen, whichever browser I use and however many page refreshes I try.
