I was advised to take a class I had taken some yea...

I was advised to take a class I had taken some years before. My advisor apologized when the mistake was realized and gave me a letter of recommendation to give to the board in an effort to get a refund for the class. The mistake wasn't realized until I called to inquire about my next semester plans. This was an 8 week course, so it was already completed, with an "A", by time we found the mistake. When the board reviewed my attempt to get a refund since they can't really give me the time back, they denied it, saying I should have withdrawn in the proper time frame. Why would I withdraw? I didn't even know I needed to!!!! I explored other options but was told no to all of them.
The bookstore over charged me for a book that I had already purchased through this easy online book package they offer. I was unsuccessful getting that money back too.
So disappointed.

Their instructors are fair and I have enjoyed my classes.

This is also the Metro campus I'm referring to.
