It never ceases to amaze me how some folks are literally their own worst enemies.
To be clear, I wrote my book, and they paid me my advance, in full. Three months before the publication date, the PR department called me up to “coordinate our efforts.” But really, their call was just about giving me a list of what I was going to do to publicize the book. I asked them what they were going to do. They had no idea. Seriously. They did not have a written plan, or any list, and when I pushed one of the people on this first call to give me examples of what the publishers would do to promote my book, she said “newsgroups.”
I assumed I was misunderstanding. I said, “You mean like newsgroups from the early 90s? Those newsgroups? USENET?”
There was probably something in the contract that said if they dropped her, she got to keep the money.
The hardest & most time-consuming part of self publishing is finding an audience and getting that initial push. It takes more time than writing. That's where you miss a publisher.
