Stolen Artwork

It has recently come to my attention that one of my products on Zazzles (as well as other works belonging to other people) have been used without my permission on a product for sale on Amazon.com. I contacted the company but they didn't seem to concerned with my complaint as they are still selling my work on their products. I have contacted a few of the ‪#‎artists‬, ‪#‎Amazon‬ & ‪#‎Zazzle‬ but I am not sure what they intend to do about it. I will keep you updated. Here is the link for VintageSh0p:
