Can't use my account properly!

Hello,
I haven't played Warmane for a long time and before 1 month I started again. When I entered in my account in the Website there is one message that says I am banned for something.
-Your IP Address (5.152.29.111) has been suspended for 10 years 10 months due to Compromising account djedovalula, coin theft.
First, I have never entered such an IP and second, I have never stole anything.
Now I cannot use my vote points or buy some coins.
I hope this is the place for this message, or tell me who/where I need to contact to resolve this issue!

Best Regards!
