Query: The Collapse of Ancient States and Civilizations-returned the book

this copy is small print, difficult to read. I returned the book and am still waiting to hear back from amazon.com to return my money or just give me some credit.also your suggestions are not very clear to follow (i.e. tag this product) what does it mean and how to do it?I tried calling you for customer help, no such thing, tried to email, it didn't work.Have you got too many customers to care???Agnes Denes
