Unfair ban

when i was playing ground realistic battle one of team made use me as shield then he tried killed me with helli and i deffend my selffe. then i turn on war thunder today and i’ve been banned.

It doesn’t work like that, for things like disturbing or writing strange things in the chat at most you would get a ban for 30 days, that is, you just had to cheat and use some external programs.

i playing war thunder around 2 years and i never used hacks

Well, I do not know to write to the support, and not on the forum because no one will help you here, I once got a ban for 30dni but the chat, so no
