seller  asked me to pay him direct into his bank account, which I did, £120 for the Carbon fibre Ducati rear mudguard. I've tried to raise this with Ebay but I only get a bot. I just want to speak to someone regarding this? I'm raising it with my Bank to try and get my money back. 

The seller as also resisted, and blocked me from bidding. He's ignoring all my messages. This shouldn't be happening on ebay. Please help
