How much does it take to prove a For Profit Private College is not keeping to their own contract which is their :Handbook?

I have been seeking a second degree with a for profit private college for over two years now. I have had three incidents occur , actually four but only three officially documented at the school, the fourth one is documented by me when it was sent back to the school and was ignored (an appeal) The school has failed to follow their own handbook policies, violating CCNE accreditation standards, chastised, humiliated, ignored request for help because I feared being targeted and retaliation on campus by a "certain group of faculty and staff". Now being withdrawn from a class w/o my signature, not suspended but was told I could not be on campus, formal complaint filed by me, formal complaint not acknowledged, and no response and its now been 15 days according to their handbook they have to respond. I've made the worst mistake of my life, not to mention time is being lost as I sit and wait on them! Please offer advice other than filing complaints (I've contacted FBOE, CCNE, ETC.)
