It's not clear what re you asking?
This is your third posting here about this generator. You have accepted that there's nothing further to be done through eBay, and have been advised about contacting your payment provider or the CA.
Our role here is to try to help other members with eBay trading issues. Good luck with your efforts to pursue your claim against the seller but this is no longer eBay matter. Unless there's some way in which we can help you need to be advised by the CA or a solicitor now.
