I bought an illegal product on the App Store! Help!

Hi, I downloaded GN Plan on the App Store.. .since this is an Apple approved app, I assumed that it was officially licensed by Namco Bandai. However, to my horror, I just found out that this is an ILLEGAL PRODUCT which is in violation of international copyright law! Furthermore, I have made several in-app purchases. Obviously, if I had known that this product was unlicensed and was possibly under lawsuit, I would not have spent any money on it! ... What should I do? I have already contacted Apple, but their "reporting copyright violations" section only allows reports by the copyright owners or their representatives.

I was basically sold a counterfeit, knock off product, through the Apple App Store. Surely this is not legal???

Secondly, I hope that Apple will immediately BLOCK THIS APP and all in app purchases and downloads! ... stop aiding criminals, Apple!!!

... for the community, what do you advise me to do at this point? Continue to contact Apple support? Contact a lawyer? Try their legal department?
