Scam Attempt?

Hi, today a guy contacted me on steam claiming I bought one item from him on the steam marketplace but he never ge the money.

He also shown me a screeshot of his marketplace history which shows me buing from him ~600$ worth some game item... and the only thing I buy on the marketpalace are the cards I miss to complete a collection to unlock a medal.

The screenshot was showing my avatar and my steam name (only the avatar frame was not correct), sensing a scam I've reported the user and stopped all the communication with him.

Does anyone else here had the same experince?
