So long story short... hacked on Monday... 6 mails and 5 days later everything is the same. Tried to call to the support phone.. oh surprise a voice machine

Ok so on Monday i tried to log in to my account that I been playing since beta (also paying since it went live every single month). Password didn't work.. thought it was strange so i tried to changed the password. No problem password changed. I manage to enter and i find out i got 1.5 million stolen from my bank. Made a support request mail asking for help. Since it was late i assumed no one will reply so i went to bed. The next day same story, password changed and this time the wipe my whole account, gold, pots, items, everything it wasn't bound. I make a new request and this time they just blocked my account and canceled my subscription. Been sending mails since then with no reply.
Cant believe that they treat a loyal customer like this... so disappointed with eso right now, was so confident that my money was going to the corporation so they could give a quality service...
Since no one answers the phone or my mails i had to take it of my chest. Not saying im quiting the game since i still have a small hope that ESO will come thru and restore balance to the world they control giving my account back and restoring everything they stole from me (if they ban the ones that received my items the better).
Since i have no viruses at all on my computer or keylogger or anything... how did they do this? They hacked ESO data base? Its impossible they knew the secret question answer... even i had to think really hard to remember what i put on the game on December 2013.
Anyone else experienced something like this? Is ESO database compromised?
