Okay, on the 20th floor are :

Thomas Klinke Immobilien GmbH -> tk-immo.de
loqio GmbH -> loqio.de

On both websites are phone numbers so I called them. loqio GmbH phone is just playing music and a message that someone will pick up the phone but after 5 minutes it did not happen. But when I called the Thomas Klinke Immobilien GmbH it got interesting, because the company owner himself picked up the phone. Since you should be on the same floor, he did not know anything about a company called "SmartGenie". He said the only company on the same floor is loqio GmbH which is a call center.

EDIT: The managing director of loqio GmbH just called me back, he saw my number on his phone. He never heard anything about SmartGenie as well.


What now?
