[Resolved]  Sony Speakers From eBay — Not genuine product

I have purchased Sony Speakers (Item #[protected] from ebay site but these were not genuine. I have opened a dispute with ebay but no action has been taken against the seller - he is still selling un-genuine products of reputed brands . Please advise me in the matter - what course of action can be taken against these fraud sellers. I am also surprised that Ebay has not taken any action in the matter as they are earning good commission on these sales.
