Scam Report

Report Type: [Money] PayPal scam or scam attempt
Virtual item type involved: [TF2] Team Fortress 2 Items

Accused profile: 76561198028188313 (Matheew)

Victim profile: 76561198011921937

What happened? Description:

I sold him 90 TF2 keys trough PayPal. He went first with the money and then I gave him the keys.

Proof of me processing the items to his account: steamcommunity.com/profiles/76561198011921937/inventoryhistory/?p=3 (it's in the middle of the page or just Ctrl+F his current nickname (now: Matheew))

Later on he charged back as can be seen on the screenshot attached to this report.​

Provide Evidence:

Screenshot of his note: "Bought 90 TF2 keys" which I hope counts for trade agreement, since I don't have the chat window history or screenshot. Or I just don't know how to access it.​
