Thank you for sharing your situation with the Wefugees Community!
First of all, I am really sorry to hear, that nobody in the LAF or at the police stations could explain you what is happening and where you can go.
Are you still in Berlin? Please, if you hurry you can still find a refugee counselling office before closing. The KuB might be one option, but there are many! Check this website for more contact details. I am sure they can help and explain you everything. Otherwise please return to the LAF and ask for someone speaking English! Do not let them send you away without any information again!
Good luck for you and please get back to us with any further questions!
