I feel you on that one. I released a short story that is a prelude to my novel and made it free on Smashwords and had it listed as 0.99 on Amazon. After God only knows how many reports of a lower price failed to accomplish diddly, I finally contacted KDP directly and explained my situation. I had to do this twice too. One week later, they finally matched the price. Needless to say, it was a real pain in the rear to do, but it got done. Best of luck!
