I ordered Abbott's Understanding Analysis. The book I got had very thin paper, considerable show-through and inconsistent and not always that crisp font quality. I made a complaint and they escalated to their "quality team". They promised I get a new book with "upgraded paper and print quality". It arrived today, after three months of waiting. No upgrade of quality whatsoever. The same paper thickness, the same print quality.
Why do they treat their customers this way?
