You can go ahead with the plan of yours to initiate legal actions but however, I would suggest that you have a backup job option as later on things might get bitter and they may fire you. Further, once that is secured, you can try to just send a legal notice and ask for repayment and compensation and if they agree, it is good otherwise you can go ahead with your actual plan.
