I’m experiencing the same issue, but I have now been stuck for over three weeks. My old Apple Developer membership expired, and I only need to renew it to transfer our existing live app to our new company account. Every renewal attempt fails with “Purchase Not Completed, submit a request to Apple Support for review.” I’ve submitted multiple support requests without receiving a reply for weeks. The contact page offers email only; phone support is unavailable. This is blocking the transfer and preventing us from updating or distributing our app properly. Has anyone found a way to get this billing review escalated or receive a response from Apple?
