Facebook ruined my business, ruined my company,it banned all of our company's groups without any reason.

My company originally operated a group-based sales platform for motorcycle and car parts, with over 600,000 members. Last July, Facebook banned all of our company's groups without any reason, causing our orders to drop by 90%. We tried to rebuild the groups and post in other interest groups to try and regain customers, but now all our employees' Facebook accounts are being blocked by Facebook. Any posts on social media are subject to review. Administrators of other social media groups say Facebook puts posts in spam and doesn't approve them. I even can't post in my own family group. We spent a lot of money on Meta advertising to promote our company groups, and we filed lawsuits against Meta through several US law firms, but to no avail. This year, my company went bankrupt. Yes, I'm unemployed, and I don't know what to do
