My bank just took all my money?

I filed BK and included a business credit card debt in the BK. I was the sole owner of the llc. The bank just "off-set" the amount owed on the cc by taking the money!! What can I do??? THe bank said that on page 5 of the cc agreement, they reserved the right to do so. I thought I was protected by the BK. Now I am back to square one. Is there anything I can do to get the money back??
