Phil Mayer at KDP PRO Inc. charged me $10,700 for marketing my books. After I had worked with him for a few months, he asked for another $5350. Because he had not done any meaningful work up until then, I refused. He then stopped even the pretense of work and refused to return any money.
Prior to my initial investment, Phil made the plausible argument that all Amazon KDP companies must have fully satisfied customers. If they don't, Amazon will revoke their rights to use the Amazon KDP name. That is garbage. Amazon had no interest in helping me get my money back or in punishing this particular franchise.
Normally, my credit card company would be able to get my money back because the company had not provided any goods or services. However, that was not the case because my payment went through Payoneer., I have since learned that the only job of Payoneer is to transfer money outside the US, which they did. Since Payoneer has no responsibility to perform services for me, my credit card company could not touch them.
