What happened? Description:

I was approached with a Trade Offer on a Trading Server. They asked for all of my taunts and my 'Ap-Sap' in return for a Strange Festive Scattergun (https://backpack.tf/stats/Strange/Festive Scattergun/Tradable/Craftable/0) worth about 21.5keys which is proportional to the items I was asked to sell.

Instead, the trade offer actually had a Strange Festivized Scattergun (https://backpack.tf/stats/Strange/Festivized Scattergun/Tradable/Craftable) worth significantally less than the other only valued at about 1 key.

I only play TF2 casually and nowadays rarely so I thought cashing out and selling the keys onwards would be a good plan.​

Would also like to tag in that users on Backpack.tf have very recently began reporting suspicious behavour similar to my case. https://backpack.tf/trust/76561198145769557

I cannot find a way to re-open the chat window with the user. Besides, I'm unsure how to have Steam show the full date of a message.
There is a date found within trade1.png. (It is todays date).
