IF you paid with pay-pal I would make that claim VERY quickly you have 45 days from payment sent to make it. IF you have paid with some other form such as Credit card you can have the Credit card company Withdraw the funds... Say you never made that payment and they will look in it.
I have done this before on other non tank related sites... AT least it wasn't a 190.00 Kit like I ordered, I got my kit 2 weeks from ordering and it was Missing parts and destroyed!!!!! I sent an E-mail to the company who made the kit and there Playing E-mail Tag with him.

I hope it works out for you... By the way I forget who it was but someone on the forum mentioned it took 9 months for there parts to come in. That is to long to wait!!
