Treat it as theft and see how to deal with that.

Be sure to read and follow their directions, and your worries are over. All of the search engines must respond to a valid DMCA notification, and each provides a means for you to file a request.

Once you have filed the notification all you can do is wait, so the sooner you do this the better for you. You can also file a similar notification with the site owners ISP or host.

In most cases of copyright infringement (with my material) there is no contact information provided on the offending site. That information isn't necessary, and as you may have discovered, it's usually pointless to try to get someone to remove your material. You don't need to spend a minute of your time contacting them, if you don't want to. On the other hand a friendly gesture may always be considered as a first option, and there is evidence that this approach works.

Either way, the formal notification process has been bulletproof in my experience.
