100% undeserved pernament ban

I received a permanent ban for allegedly selling coins. I rarely use the transfer market and hardly ever sell cards, but yesterday I decided to sell two. I did not make any transactions that would violate the Terms of Service. On the day I was banned, I sold two cards: Vieira 97 for 239,000 coins (market average is around 270,000 – I sold it slightly cheaper so it would sell faster; it's not my fault that cards don’t sell well on PC), and Olise 97 for around 230,000 coins (in line with the current market price).

All transactions were made within the allowed price ranges and on a single account. I did not transfer coins, I did not buy them from third parties, nor did I engage in any illegal activity. How is it possible that this was considered coin selling?

I hope someone from support sees this, because talking to a bot and reading generic responses saying I broke the rules is far from pleasant. I’ve been playing for over 10 years, and for the past few years with EA Play Pro – always fairly, never had a ban or warning – and now I get permanently banned for selling two cards at normal prices, while regularly paying for your game? This honestly seems like a matter for a consumer rights advocate...

So I hope someone from support sees this or that it gets escalated, because this situation is no laughing matter for me :)
