Welcome to the Wefugees Community and thank you for reaching out to us.
Before hiring a new lawyer, you may contact the Refugee Council Munich to get a second opinion. From my experience, changing the lawyer sometimes only causes additional costs and confusion. On the other hand you should demand transparency and reliable communication as well. The Refugee Council offers free of charge and confidential counselling services. Please follow the link for the contact details.
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
PS.: You are of course always welcome to post in German language on this platform as well.
