[Account security] Someone is trying to login in my account every 1-2 weeks!

Hello Warmane!

I am player of your servers with run and stops period of gaming. I got couple of characters in different expansions. Not great - but i invest my time and effort.
The reason I am contacting you today is because I don't feel safe/secure because someone is trying to login my account several times. How do I found out? My two step authentication is ON and I am receiving emails with code. Last few months when i had couple of attempts per night even with two-step authentication I've changed my password. I don't feel safe because there was not a long time after and the attacker knew my new password as well. This is impossible - I didn't shared any of my passwords in my life with anyone. Someone is hacking me all the time. I can tell you my ip i'am logging from years and i can attach photos from the emails with their IP if you can assist and investigate these attacks please!
I am looking forward to receive response from you as soon as it's possible.

Thanks for the understanding in advance.

Kind regards
