modernproducers.com Don't want to pay us for our sales on their site Los Angeles California

They have some of our products up for sale on their website for a whole year now & they don't want to pay us for the sales they've generated. They also were selling our products on another site & tried to tell us that out of the whole year they only sold one copy with our product in their Kontakt Kollektion Bundle, then they went & made a second Bundle of Kontakt Kollektion. Now, with them making a second bundle of Kontakt Kollektion, does that sound fishy or what? They must've sold pretty great on their fist Kollektion. Our product in the Modern Producers Bundle is called HYDRONEXIUS our other product is ALIEN & adrian at modernproducers.com is trying to keep a whole years pay from us. He put our product HYDRONEXIUS in the Kollektion when he bought out Bigwerks.com, we used to work for Bigwerks.com & thats how our Products were forwarded to him. I have all the emails from bigwerks as well stating that bigwerks had sent Modern Producers our whole product lineup SOUNDSHAPERZKITZ
