Wrongfully banned for buying golds for griddy to glory objective

So about two weeks ago when all useable gold cards were extinct or max price because everyone was buying them for the griddy to glory objective, I bought and sold a full team of gold cards that I used for those games, EA have decided that I was transferring coins and I’ve put through two cases explaining the reason the golds were bought and sold at this price however both cases have just been declined with no explanation or (human) response as to why they are actively ignoring a wrongful ban. Just needing some sort of help as this means I’ll be hindered on the next games transfer market on the web app, all because of a ea ban mistake. Cheers
