I just don't know where to post this.

Ok, so let me begin. I signed up like 1 year and 5 months ago, creating an account on mining.bitcoin.cz, for the purpose of mining, of course.
For about 2 months I used 'miners' on several linux operating servers and reached the ammount of 1.51 BTC. Its value was pretty low back there and I left all this stuff, doing something else.
A few moments ago, I checked the BTC value and I was like WOW, WTF. Didn't even remember how much I had on my account, so I logged in to see it.
But surprize, 0, nada, nothing. And a payout log of 1.51 BTC to this address: 1PJ192n9gs13nHNNSz4Bo5AMoYGBrUvK1N, at 10-16-2013.
No, it wasn't me doing that, I didn't log in since 1 year 3 months ago, the mining process says it just this way.
And no, nobody else could know my username/password to that.
Now, what in the hell just happened? Did they just stole my work and money or I'm too stupid to see what's going on?
Please, if anyone can help or know anything about this, say a word.
I don't even know where to complain, there's no Support section.

Hello,
I see that this is frustrating you and seems to be a problem. Well the thing is that if your money is stored on your wallet online it isn't AS safe as having a downloaded wallet. This has happened to many people and it is because of hackers and others finding ways to take your money. Sadly, now that it has been taken and you no longer have it, there isn't anything you can do. The point of mining is to make the server more secure and secure from hackers taking bitcoins from people like they did for you. But now Bitcoin is so much safer due to so many miners. So you won't run into this problem again with bitcoin being as safe as is now. Bitcoin is a really great investment and if you are still up for it you should invest in it. 
 Thanks,
           Matt

There's your problem.

This has absolutely nothing to do with the fact OP had his money stolen from an online wallet.
