EBAY HELP PLEASE!!!!!!!!?

[NONAME]

I purchased an item off of eBay the 1st day of February this year. The item arrived broken and I contacted the seller. The seller didn't respond so I proved them wrong with evidence and they still didn't respond. I opened a case and then the seller quickly responded saying that he would like for me to return the item. I then contacted eBay after he neglected to provide me with his return address after I asked for it twice. eBay gave me a free shipping return label and I sent the item out. I was refunded. A week later I got the package delivered back to my house because the address that the seller provided on their account was incorrect. I didn't want the item since it was broken so I listed it for sale through my eon selling account. Now, 3 weeks after the original case was opened, the seller contacts me asking for me to return the item. It already has 12 bids on it. WHAT DO I DO?
