Signed up for a free trial on May 28, 2026. On June 2 I received an automatic renewal notice for $499 due on June 4. Immediately tried to cancel. The cancel button loads briefly then grays out completely with "Something went wrong. Please try again." The billing page shows an internal backend error: "This account does not have a valid Zuora account associated." The Delete Account option recommended in their own support guide doesn't exist on my account. Tested on 3 devices, 2 networks, a VPN. Every other page works perfectly. Only the cancellation pages are broken. Their AI support bot stopped responding when shown the backend error screenshot. Filed support ticket #1517524 with no human response. * This is not a one-off bug other Trustpilot reviewers report the exact same frozen cancel page before their trial ends. SimilarWeb even responded to one saying they'd "simplify the free trial cancellation process" — yet here we are. Filed an FTC complaint. Report #202408814. Date of experience: June 2, 2026
