Achieve Test Prep Excelsior College quadrupled its fees adding $8,000 to they price of my College program Achieve Test Prep won't refund those that can't afford the the additional fees St. Louis Missouri

I contracted with Achieve Test Prep for test prep to pass College class exams- I paid in full because of a discount to pay for the full program.  I asked at the time of the contract what would I be charged if I find out this doesn't help me. After a couple of classes – the College Achieve Test Prep  paired me with Excelsior College quadrupled its fees  for the 8 required Nursing classes –going from $375 to $1510 per class adding $8,000 to the total cost of the nursing program. A significant change I could not afford  Excelsior College is offering its own –online classes  - little more than on-line message discussions and homework assignments.  Achieve Test Prep expects me to pay the quadrupled fees and pay for their classes as well.  - I paid Achieve Test Prep over $11, 000.00 Excelsior College expected about the same in test exam fees and other fees.  The difference is that with Excelsior College You pay for each class as you take it.  What I didn’t understand is that  Achieve Test Prep obligates you to cost of the entire program, something they never made clear.  I took only 2 classes. Wants to keep $9,000 as “my contracted obligation whether I took classes of not.  When paying for the program I was quoted to pay $375. pre-class –if I paid in full. Nothing was said about refunds –but when I asked - I was told that my refund would depend on how many classes I had taken.  I was never told or personally considered that the only school Achieve Test Prep used for my program could or would quadrupled its rates after I took only 2 classes.   I am a 58-year-old LPN - I wasn't trying to get over - I just needed a reasonable way to advance myself in a way I could afford and manage, I do know a couple of BSN nurses that are successful that did an online program - Seemed legit at the time.  My program contained 17 courses I took 2 of them before I found out that Excelsior College quadrupled its fees and achieve test prep could offer no alternative schools.  In the hope of saving other people from this $9000 loss, I understand that those that have loans must continue to pay.
