It's too late to report this to eBay or to enforce any refund from the seller, as you have gone well past eBay's 30 day MBG, Money back Guarantee policy.
You can try your payment provider now for help with a refund.
I know from this experience you'd know what to do next time, but always wise to check an item's authenticity on receipt of an item, then as above, you have 30 days to return it to the seller, at their expense, for a full refund.
