Dear @TayLima,
Welcome to the Wefugees Community and thank you for reaching out to us.
As far as I could find out, the Landratsamt (immigration office) in München should be still responsible for you being registered in Pullach. Maybe you can contact the "Helferkreis Flüchtlinge und Integration" in Pullach in case you face difficulties. I am sure they are happy to support. You may find their contact details here.
However, please don't hesitate to get back to us with any further question.
All the best,
Meike
