It's a long story. Few years ago a person under a company from U.K. contacted me via email and he said he wanted to promote my artworks on their website. Later, I found out that the website was selling it, instead of promoting it! I asked who gave them the right to sell the artworks and where did they get the files for the artwork from. Then, the very same person who claims to help to promote my artworks told me that he was the one who put it up on the website. He never told me that he was going to sell my artworks. When I told him that without my consent to sell the artworks, what he did was wrong. Then, the artworks were removed from the website. Now, I just found out that another website under the very same company is selling my artworks. @netgeo_wild buy it from there. No one is giving a reasonable response till now.
