My account was hacked due to your incompetence

I demand my account to be returned immediately with my stashes intact. If you fail to do this I'm never supporting a product made by you again. I tried logging in today just to find that I no longer can. I tried changing my password and confirmed and after changing it, your game tells me thats an "invalid login". I believe I've been hacked due to your negligence and lack of enough security measures to prevent this from happening.
