It looks like something that might flatten out with some pressure. Yeah you got ripped off, agates are made of rock, not plastic. If they were real there would be variations of clarity, some you should be able to even see through and the inclusions would be a part of the stone instead of separating the stones. Get your money back if you can, if you can leave feedback, I would be like : IT'S FAKE! OMG I'm so mad, neg. neg. neg. or something like that.
