How to delete Campaigns account

Hello,

We have a company Zoho account with CRM and Campaigns. However, I accidentally went into my company Zoho account to the home page, selected "All Apps" at the bottom and then set up a Campaigns account by mistake. I was trying to access our company Campaign area but was not linked to it yet.

Now my administrator cannot link my company account ID to our company Campaign account because I have accidentally set this up.

How do I fix this?
