Hello I returned some jeans to a seller within 8 days without raising a request through Ebay. The seller received the jeans and messaged saying if they were delivered on Friday a refund would be made on Monday. Over a week later I got a request from them saying raise a returns ticket through ebay, even though they had already received the jeans so I left it. Having still not received a refund, I opened a returns ticket which was immediately closed, the seller saying it's after the 28 days returns limit, even though I have proof the package was delivered to them. They are now ignoring my messages and I do not know how to raise help/a dispute help with ebay. It seems that because the returns ticket is closed I cannot raise a dispute resolution  through ebay. Trying to get help from ebay I just get the AI bot.
