Hello @Nodosaria,
Your account can be temporarily sanctioned for varying amounts of time due to repeatedly breaking the Siege Code of Conduct or disconnecting from Ranked matches.
The length of the ban will depend on the offense and how many times you have broken our rules.
I understand you said you have not used the chat or voice char recently, but we are unable to lift any temporary abandon sanctions, we do not have the ability to do so, this is solely managed by the game, so you will need to wait the specified time in your in-game ban message, before you can play again.
