The problem is not about CASE. You need to have substantial evidence to fight a case, any case. I approached CASE 10 years ago re my unhappiness on a private school. I requested refund of my course fees as i felt short changed after enrollment. Many trips were made to CASE and there seemed to be no case initially because i simply have no strong evidence. The people at CASE were hand tied. BTW, I am not related to CASE in any ways. One day, i managed to find some evidence in my favor and CASE arranged a mediation session between their volunteer professionals in the law industry and i managed to secure refund for my fees paid. Sometimes i think there are also other avenues to seek redress, small claims tribunal..etc. But be prepared to go through hassle and and test your endurance.
