Query: Dissapointed

I haven't been able to watch this product. i didn't realise when i purchased it, it wouldn't play in my blu-ray player. i then asked to exchange it for a regular copy and i was more than happy to send back the orignal one i had received. but instead i received yet another blu-ray copy and haven't been able to get in contact with the seller ever since.
