eBay

They never tracked and buyer says it never arrived . How do I make a claim

How do I change tracking number? I had a jam and can't reprint so I just mailed but I have a new tracking number

When creating a listing, sellers can add their preferred shipping method, locations they ship to, and an estimated delivery cost.

I made a offer, seller made a counter of 10.99, I then made another counter offer of 2 autographs instead of one for $20. Seller expected but only mailed one autographed picture. Whats my options because they haven't responded to messages so far
