Diablo immortal,banned for ever,for no reason

So i was waiting for the Diablo Immortal patch(20 july) and after i downloaded it ,i got the temporarily suspended error message.
So i contacted blizzard and they told me that im banned for ever from Immortal.
I asked them the reason,and they never told me why i was banned.
They just said,we reviewed the situation,and that the ban is for good.
I am (was) a legit player,spending many hours a day to enjoy the game,
and they treated me like garbage.
I even told them to prove that i did something illegal or bad behavior or just tell me what i did wrong.
I was banned and never got the reason…they should at least tell to the people what they did, so they will not repeat it in the future.
