Problem with Amazon, need advice

[John]

Hi everyone, I really need some advice. Twice in the last two weeks Amazon has lowered the price of my $4.99 "Rose Of Skibbereen" novel to free, because they keep price matching to the wrong book. I have a three chapter "teaser" version of the Rose book that is free, but Amazon keeps mixing it up with the $4.99 version. They see it offered for free on Sony or B&N, and then they make my full-length novel free. I have to email them about it, then they take two days to fix it, and in the meantime I've had 793 free downloads of my book. Here's my question: should I change the cover and/or title of my free book? The title is "Rose Of Skibbereen: The Beginning" and the cover is almost identical. The ASIN number is different, but that doesn't seem to be helping. And, can you change the title of a book that's already published? Do you need to re-publish it? I hope someone can help, because I'm afraid this will happen again and I'll lose more sales.
