Business Email User - delete

How do I delete a Business Email User?

Google Business Email Subscription

My email subscription is about to renew. I have three users but I no longer require them. I am trying to remove them from my account so that I don’t have to pay the renewal on all three.

I have tried to delete the users from google and from wix dashboards without much success. I managed to delete one, but it is still linked. I want to make sure only the main Account is renewed, not the subsidiary ones. I tried cancelling the subscription, but it only gives me an option to delete the whole account.

Please help:)
