I would like to say that I've made contact with the owners of the first site and image is no longer there.
For other we site, have you tried to download your EPS? I cant test using my iPhone right now, but most "free" download sites are just a scam takes you to another site, then another and they ask you to register and pay x$ to be able to download the file, and even then I am not sure the file is even available.
I'd suggest you test this, then of course make yourself heard to site owner and to Shutterstock.
Sucks to have to do That anyhow... Good luck!
