Finally! After almost 4 days and 7 help requests i got a reply from Google:

Hello,
Thanks for bringing this issue to our attention. We have forwarded the information you provided to the appropriate team for further investigation. We appreciate your patience, and we apologize for any inconvenience this may have caused.
Sincerely,
The Google Team

Although it is kind of a progress, it is still far from providing any solution.

In the meantime i learned that i am not alone in this 502 boat.
