My game account was mistakenly banned, but EA ignored it.

I have a similar experience.
I didn't do anything that violated the terms and conditions, I was playing perfectly normally and my account was banned.

But they just kept repeating like a bot, “We investigated, but the result won't be reversed” and the ban was never lifted.

Only a few well-known streamers and pro-gamers would restore the accounts they had accidentally banned, and they would only perform the performance that they had investigated and done their job properly.

They don't care about the general players who supposedly pay the most for their games.
They probably think they can get more money by making people re-purchase the same skins, etc.

So they have to give up now.

To avoid wasting your precious life time, and to avoid wasting your nerves by this stupid game and company, let's not get involved with this company and their games anymore, which are nothing but this kind of stupidity.
The only protest we can make is to stop being involved with this joke of a company and this joke of a game and send them to their graves and bury them in the past.

We, the users, should get out of this game and spend our time and money on other more interesting and meaningful things.

Whatever we expect from EA/Respawn anymore, we will be betrayed and disappointed.
