Hey, recently I traded with him for the May and June Humble Choice bundles as keys. Unfortunately, I received three duplicate keys from his May bundle. I haven't used the June bundle yet, but I'm concerned that those keys might also be duplicates.
When I confronted him about the duplicate keys, he initially denied it, but eventually admitted his mistake. He promised to return my money/TF2 items as compensation. However, instead of fulfilling his promise, he has been completely unresponsive for the past few days. That's why I'm reaching out here.
