If you're unhappy with work you paid for, your refund options are limited and you must go through Fiverr's internal process first, which may not always resolve in your favour.
Fiverr's Terms of Service affects consumers financially through service fees added to every purchase, and legally by requiring US-based users to resolve disputes through binding arbitration rather than court. Fiverr also retains a broad license to use content you post on the platform, and can suspend or terminate accounts at its discretion. You can opt out of the mandatory arbitration clause by sending written notice to Fiverr within 30 days of first accepting the Terms.
