And I clearly said that in the first post.
My issue is that I brought this up before, on here, MCS responded asking for proof. So here you go.
What were my options in contacting them?
1. I send them back for a refund. Waste of my time and theirs for $5 books. I can sell these and break even. It's a chance you take with any buy/sell transaction.
2. I raise the issue. They refund my money and tell me to keep it. Then I sell them, profiting off of a zero dollar investment. I don't think that's very ethical, do you?
The issue was never about the money, it was about the grading.
