That is surprising - sorry your experience was not good.
I have written a lot of books for publishers and I have some advice that might be useful in the future: always either meet deadlines or give a heads up if you expect delays; thank editors whenever they catch an error and make good suggestions; don't ignore editorial advice if you dont agree, always respond with a reason you are ignoring advice; as much as possible make some personal connection with editors even if it is just a few minute talk about family, career, interests, etc.
I always view publishers as my customers and treat them as I do people who pay me to do consulting work.
