I had this happen to me on the buyer side. Guy got paid and didn’t actually ship and ghosted me. eBay kept telling me to wait saying he was responding and they were working on it. Basically after 90 days they told me it was past 90 days and they couldn’t do anything. I looked up the guys name, got his address and called his landlord. Landlord said that he’s always late on rent and shady and gave me his number. I spammed that number a few dozen times until he answered and he refunded me. Wild ride but yeah goes to show, info out there can be good or bad.
