I messaged seller to ask if I could refund. They sent me their address so I posted it back. One week after delivery, no refund. I messaged seller and they said no refund since missing part of the item (which is untrue). I have proof of postage. I want to complain to ebay but I am stuck because it appears I can only complain if I raise a return (which I cannot do since I have nothing to post now). What are my options? Thanks.

I had a callback with Ebay this morning and it's already been resolved. I got a full refund. I really appreciate the help you both gave.
