stuck in apple business connect

We want to add a Book button to our customer Apple Maps annotation and need a business account for this. We previously purchased the developer account using a Google email. Now, Apple Business Connect requires moving it to an email under our company domain. We've tried several times, submitted all required data (domain verified, with verification evidence), but we've been stuck on this step for about 8 months. Does anyone know how to reach a support agent to discuss and resolve this issue? Our company is in Greece.
