You won’t get a response. It’s a known issue. It’s not a high priority…
While it is theoretically possible for us to unmute players which might work around this, we’re not in the practice of reversing these kinds of account actions for this sort of reason. Regardless of this unexpected behavior, the accounts which have been muted were muted for a reason. If you have an extended duration suspension, a user of your account must have broken our terms of use several times. As such, the account actions will stand until they expire.
