Cannot find how to reduce subscription package from previous enrollment

Cannot find how to reduce subscription package from previous enrollment

Dear Zoho team, when I first found ZOHO I subscribed for a payed package.  However, I would not like to remove that feature.  Namely I have not found the functionality that I thought I would find.  Please assist me removing my Zoho account. I think that the system has changed completely, I do not know how to stop payment without posting this question here.
