Transfer Market bans are normally permanent. You can try contacting @EAHelp through Twitter or open a case with a live support advisor here: https://help.ea.com/en/contact-us/new/. You can also go to facebook.com/eahelphub to get in touch with support. They'll look into this for you. Thanks!
They won't be able to help with this. You'll need to submit a dispute with Terms of Service as directed in that article I linked.
