Wish this were a perfect world where everyone did as expected and right but it isn't. You are definitely entitled to reimbursement in my opinion but that accounts for nothing. I think you have learned a costly lesson and I feel badly for you. Honorable doesn't seem to mean what it once did.

The old saying is true, We are too soon old and too late smart. I know you will learn from this and be careful when choosing another Master but it was costly not only monetarily. Let's just hope something positive comes from all of this.
