Publish America PA sold my book in several countries and paid no royalties, Internet

I wrote a book in 2005 the lingerie room, and have discovered that this book has been sold on amazon, ebay in uk, powels books, indiaplaza, bondfaro.com.br, openlibrary.org, ciao.co.uk, buycdnow.co.uk, and in canada. As I live in UK PA most likely think I not discover this but I happened to look on site a week ago and discovered all the places they are selling my book - some say "last one left" and sold for 25 uk sterling.

I have received no royalties whatsoever for these sales and PA deny ever selling the book I want to report this scam as they also relayed that they would promote the book in finland which they never did although I paid $45 for it  PA is using authors to make vast amounts of unaccounted for income and scamming authors of their rights to royalties I see I am not alone in this !
