Scammed by Pinseller007

Briefly explain the trade: I payed him $3.50 for a AUS pbp pin. He gave me an invalid pin. Even though it was an invalid pin, I don't believe his intention was to scam, as multiple other sellers also stated that there was a problem with their supplier and were giving them invalid pins, so I also believe this is the case with pinseller007. This trade took place a few days ago; I waited to see if he could find out what the problem was, but never replied back.
How they scammed: Invalid pin

This happened to him before, I've PMed him to refund or replace your pin. If he doesn't within 3 days, then let me know I will ban him. Please keep us updated.

 

Pinseller007 has issued me a refund.
