I think I nearly got scammed on ebay. Bought some furniture but they had strange messaging, only very late at night

they did not give me the information I wanted to pick it up but demanded codes that would enable them to tell ebay the transaction was completed. I even asked 3 days. No information.

I cancelled and got my money back. Then they send me a message like 2 minutes later and they were very angry.

But they did not lose any money. They still have their items.

the fact they were very angry makes me think that yes, this was a scam.
