Could my suspension be removed?plz

It depends. Punishments are generally not removed/lifted unless there was some form of error on Riot's end in giving them. If the punishment was deserved, then it will not be removed.

If you want, I believe you could submit a support ticket to ask for them to take another look at your punishment, but if Riot still deems the punishment is deserved, then it will not be removed.

If you have any other questions, feel free to ask.
