How to get unbanned

Hi,

I recently got a email from blizzard saying I got a permanent ban on overwatch.

I haven’t played the game in about 40 days, and have never been banned before, not even a silence.

I have tried to appeal it 4 times but get the same response everytime saying they will not overturn it and I have been banned in accordance with the terms and conditions.

I don’t know what to do anymore, I haven’t done anything and am not toxic in games, even so I haven’t been playing at all for over a month.

They don’t seem to even acknowledge what I’m saying about not playing the game in a month.

What do I do?
