So I sold my BlackBook on ebay or what not and Paypal threw a hold on the funds. So I shipped it and the guy receives it today and tells me he doesnt want it because the battery is bad. There is absolutely nothing wrong with the battery and I think that he might be trying to swap out something with the computers. He says he has the battery plugged in and it's saying battery is not charging. I've never had that problem before and that's why I think there is nothing wrong with it. I just got the computer in August of 2008. Anyway, as far as eBay goes, what kind of protection do I have if he sends me another computer other than my own? I have the serial number for my computer and everything. And Paypal has a hold on the funds so if he disputes it they will go back to him and he has my computer so i'd lose completely what can I do about that?
