How do I close a branch in Poland?

Hi there,
Does anyone know how I can close the branch of a company in Poland.
I found lots of information on the web for how to open a company etc.. but none seems to exist on closures.
What I am looking for is what is required (procedure) in closing a branch and whether it needs to be done in person or electronically, how much it costs etc.

Many thanks in advance for your help!
