I am not a native English speaker and hired an editor to correct the style of a book that is being published. However, this editor didn't work in the final version of the manuscript I sent but rather on an old draft I had sent for a quotation. Additionally, the returned manuscript had many added typos (at least 20 in one chapter).
Since the editing was done it an old version, it is now completely useless to me. How should I handle this? Should I pay for work that wasn't even what I requested?
Is it normal for an editor leave typos and expect for a proofreader to fix them?
