I gave a testimonial to an online business in which I am no longer involved with. I initially okay'd the use of my image and testimony. After receiving some unwanted attention from the testimonial I nicely asked to have it removed from the company's online sales page. The company complied within a few weeks and everything was fine. Four months later I received an email which made me aware that my image and testimonial has reappeared on the online sales page (website). I have asked, nicely, again to have it removed and I am now being ignored. I have copies of all emails of mine and from one of the owners proving that communications had taken place regarding this issue. Do I have anything to stand on? Can I make them comply? Can they continue to use my image and testimony?
