Dear @Refugee_Ingermany,
thank you for sharing your question with the Wefugee Community.
If you have not tried a migration counseling/asylum counseling office, you may want to seek the help of one of these offices. They may be able to help you. Sometimes, these offices have a specific contact person in the Landkreis or they know some other ways to reach the employees of Landkreis. These offices are such as, Caritas, Diakonie, AWO, Flüchtingsrat, or DRK/BRK. If these offices also cannot help you in this regard, then you can perhaps seek the help of a lawyer.
I hope, you have got your answer. I am a MBEON consultant. If you wish to contact me directly, you can see my profile and follow the instructions there.
Best wishes
Fardeen Noori
