eBay's money back guarantee only lasts for 30 days from the latest estimated delivery date. So if bought on eBay, it may aleady too late to open a case, but if there's still time you need to do so very urgently.
If you paid by PayPal,their buyer protection for undelivered items lasts longer, for I think still 180 days. Or if by credit or debit card, your card issuer may be able to help.
