War Thunder Unjust Ban and Inadequate Support Service

My 10-year-old account was unjustly banned. I am asking for an explanation. They say the evidence is confidential, and when I tell them to check my statistics and replays as proof, they ignore it.

I bought a 180-day Premium subscription 15 days ago, and before that, I had a monthly subscription. I say this, why would someone who cheats buy Premium? Also, I'm 35 years old, why would I bother with this? W** is like a saint compared to them. Anyway, my hands are shaking with anger. Now I understand that Gaijin has severely wronged me, they are not refunding my money, and the support responses are much worse.

I will report the situation to the bank, I made the purchase with a credit card. They are not even allowing us to defend our rights, they have also banned me from the forum.
