Deleted house from the tado team

Today I received an email from tado where they told me that the tado team deleted my house so all the configuration that I had but I didn't ask for this. I am the “owner" of the account and there is another person that have the permission in my tado app and that's it. There was another person but I delete his email from “my house“ so I suppose he can't see or modify my configuration anymore, is it correct?
Many thanks
