Sounds like someone's account has been hacked and/or someone else has been using your account. Steam can't just spontaneously decide to charge you for a random product.

As this is the Steam Users' discussion board, you'll have to contact Steam Support in order to get it sorted.

Steam didn't take your money, either your PC is compromised with a keylogger giving someone access to everything you type onto your PC or someone you know has knowledge of your account details and has been using your account - do you have Steamguard activated?

It is your responsibility to keep your login information secure, not Valve's. You need to do a complete scan of your system and find out how that secure information was accessed.

Step 1. Activate Steam Guard and unauthorize ALL machines. Then allow your current box(an email will contain the security code).

Step 2. Get someone with security knowledge to evaluate your computer and figure out if there are any scripts running or some form of remote control. (You might even get a speed boost out of turning stuff off and/or uninstalling). If you have any filesharing (limewire, torrent, windows sharing) that you didn't know you were doing kill it... WITH FIRE. If you have some form of webserver installed (That also includes checking for IIS) and you know you didn't do it repeat the above step(the one involving fire).

Step 3. Find a decent antivirus and do an extreme anal scan of every file once. Some default to only exe files, so look before you scan. (this will take hours)

Step 4. Change your steam and perhaps your Sindow's password and don't tell anybody else what it is or even what your steam/Windows login account name is.
The reason this is last is in case of keyloggers which should have been removed by a local nerd and/or the full antivirus scan. Otherwise you're just telling the new password to whoever it is.

Support should be able to tell you when the payment was made and by what method, but they likely won't refund you.
In addition to the other guys suggestions, remove all credit cards from your account and use Paypal instead, so if anyone gets onto your account again they won't be able to buy anything unless they know your Paypal password.

Also, check your transaction log at the link below.

thanks i will see if i can do all that and thanks to all the people who were polite unlike someone i wont mention any names (kiya) but to the rest of u thank u .besides kiya.

When you said you were having trouble launching games did it say no connection?

You should at a bare minimum

1) Enable SteamGuard
2) Use Yahoo/Gmail and enable the SMS authentication on it
3) Install anti-virus
4) check that your kids/roommate/siblings/etc didn't just buy the game

If not I recommend formatting the computer as you're likely infected with something.

I am surprised Steam does not let you see what ip adresses have last been used to log in. It would be really helpful in these situations.

You could then proxy out your connection 'pretend' to get hacked and buy up stuff.
