Hello yasevol
We understand that this situation is frustrating, especially if you believe the sanction was applied incorrectly.
However, sanctions related to the Transfer Market are handled directly by the Terms of Service teams after review of account activity. If your appeals were declined, it means the sanction was upheld following those checks.
The message might be automated but every time it's checked by a human.
At this stage, the only option remains through the appeal process via EA Help, as on the forums, we cannot remove or modify account sanctions.
Good luck.
