Enrollment not successful - no reply from German dev Team

We registered an Apple Account and started the enrollment as company. Entered DUNS number and everything. Afterwards we got the mail, there is somthing suspicous, we have to reply to germandev@ why we want to be registered. We found out, that we had a student once who started developing an app and registered themselves with company details. This account seems to be closed, but anyhow, it is mixed now. I tried to write several times to germandev@ team, but we don't get any reply for weeks.

Who else can help us? Some phone number? Thanks
