Thank you for reaching out to Jotform Support. Can you elaborate on this issue, so we can assist you better? Did you fill out a Jotform that had a purchase order? Please note that using the Purchase Order widget allows you to use 3rd party payment processors instead of our available payment integrations. So if that was your case, you may have to reach out to that 3rd party entity for your payment? Otherwise, explain further, so we can provide an appropriate response.
