It's supposed to be less complicated than bringing in lawyers but you still need to file everything, show up in a suit, and be prepared to argue your case. It isn't like you can just fill out a brief online form and get a refund. It's an all-day affair. Also most courts are only open during working hours, so you'll have to take time off, but there are exceptions to this.
Also, the discrimination thing is a result that I've not (personally) heard anyone mention before.
