Item hasn't arrived after 4 years

[bradwillau]

Over the past 4 years I've been contacting a seller saying my kite never arrived. They say they sent it twice and it was delivered, but it never was. How can I open a dispute after such a long time?

Ebay's Money Back Guarantee for buyers is valid for 30 days from estimated date of delivery, so therefore you cannot open a dispute 4 years later.
