As others have said, it's business days and we have a long weekend coming up. Keep checking the dispute each day until the option appears to ask ebay to step in. As soon as it does, smash that button. Someone with 2 feedback shouldn't be allowed to list items with such a high price. In fact, new sellers are usually quite restricted in what they can list. I wonder if his other buyer has realised they have probably been scammed too?
I don't know if it's still the case, but during the peak of Covid, ebay extended the time before you could ask them to step in because of worldwide and national postage delays. Hopefully someone can clarify if that is still the case.
