Hello,
Sorry to hear about what happened.
If activity occurred on your account you do not recognize, it may mean your account or computer has been compromised.
Someone may have gained access to your Steam account through spoofing, phishing, or malware.
We have some tips for removing malware from your computer here. It may be a good idea to contact a local computer security expert if you're having trouble removing this malware.
I can see that you have already secured the account with a password change however all Community Market transactions are final and cannot be reversed or refunded. When an item is purchased from the Community Market, the cost is sent from the buyer's Steam wallet to the seller's. Reversing these purchases would mean we have to take funds out of the seller's wallet, creating confusion and possible purchasing issues across Steam.
I'm sorry we can't be of more help with this, but we don't reverse or refund Community Market purchases and sales.
To prevent unauthorized access to the account, I recommend that you keep the Steam Guard Mobile Authenticator enabled and also review our Account Security Recommendations.
If you have any further questions, please let us know - we will be happy to assist you.
