Website blocked, but do not have an account

We are not a Cloudflare customer, but some of our users are getting website blocked messages from blocked.teams.cloudflare. We believe one of our previous employees setup a free trial for content filter that was never disabled. How can we remove or disable this?

do you happen to have any cloudflare account info for your employee?
