Missing coins and gear on my account!?

Hello, my name is Emīls Jansons, I've been playing wow on molten and warmane for several years. These last few months I didn't have time to log in, because of real life business, I moved to another country and I needed to find a job.. Now that I had to time to log in I did so and I see all my coins and gear missing, characters are not even lvl 80 anymore.
I donated about 200 coins, bought gear, earned achievments etcetera.. but now everything is missing.
Why is everything missing? Where is everything I worked for?
I'd like to have everything back, because I never did anyhing to lose it. I haven't been banned or punished.
I didn't pay my money just to lose it all so quick and for no reason. Is this how server admins treat their clients?
If nothing is returned I will never play on warmane servers and I will suggest all my friends to leave and never donate again.
I hope one of the admins reads this and answers me, because people can't even make tickets anymore to solve their problems direct.

With respect, Emīls Jansons.
