Getting scammed by institute

A company writes its own regulations different from the existing government laws and sometimes often violates fundamental rights of human.There is endless list of such things where they are violating. One such thing is done by major educational coaching industry who demand caution money at the beginning of semester. After the course is over they demand sensitive personal information like fingerprints,very important and sensitive documents like identity proof, exam hall tickets,school certificates etc. to fill form regarding getting back the caution money.Eventually we have to give our very personal information to them to get our rightful money back. They take months to process the caution money form and give it to the students after about 5-6 months or sometimes even don't give it back. As a result they cheat their own consumer.I really want help regarding solutions to these types of frauds
