There should be an option to request review by a human from persona when they reject you, also make sure you're not on a VPN and your ID is from the same country as the one you're applying from. Persona is picky with these I've also had trouble in the past when applying with an ID from a country that doesnt match the location I'm applying from. If you still run into trouble email support@retellai.com and the team can look into it.
