Zoho Sheet redirected to "Zoho WorkDrive - Create Team" dialog, now I'm signed up for something I never agreed to

A short while ago I tried to open one of my spreadsheets via the web on a Windows PC, and I couldn't. No matter which of my bookmarks I clicked, the spreadsheet wouldn't load and instead a prompt appeared asking me to choose a team name.

I don't mind having a team name, even though there's not many of me, so I just typed in a name.

Now I can get to my spreadsheets again. But when I loaded them, another page was displayed saying I am in the middle of a "Business Edition Trial". What is this??? I never agreed to trial anything. And what parts of the service I have been using all this time will vanish when the "trial" I never agreed to is over?

Blocking people's access to services to force them to click through a prompt then using that to sign people up to something without their consent is completely unacceptable. What is going on at Zoho??? How do I end this unwanted trial???
