14-Year Player Banned from World of Tanks! Accused of Racism Due to Origin

I have been playing World of Tanks since the beta server was released on September 16, 2010, and after investing a lot of time and money on the game for fourteen years, they chose to ban my premium shop. The reason for this decision is that my origin is Iranian, which is the same thing as racism. When I wrote issues, they closed my tickets without providing any kind of response. It is impossible for me to take action because they are hijacking my account. I need your assistance in doing something.
