You still got your TV though didn't you? That analogy is flawed, it's more of a case that they served the clubcard guy/s first then you lot. Unless a prime customer took your TV from your order (which I don't see how that can be proved fully).
Not yet i haven't! True i cant prove it was stock related, but your right, its more like having 10 tills for club card owners and one till for "normal" customers, if a supermarket did that people wouldn't be happy.
