Query: Too bad quality

I am from Colombia and I am studing a PhD in Brazil. This book looks like a bad photocopy, its not originally impression.It looks like a latin's pirate copy. I am very disgust and disappointment.Este libro no es una impresión original de Mc Graw Hill. Mas bien parece una vulgar fotocopia pirata como las de nuestros paises latinos. Me siento engañado.
