How do I get past mission pass items?

I just decided to use my golden mission pass right before the season reset, not realizing what it would do. Is there a way to get more of the mission pass items or unlock them after the season ends?

Once a new season starts, you cannot unlock Tiers on past Missions Passes. Your only option to unlock the current Tiers right now is to spend SG to unlock them all before the current season ends.

Try to send support a ticket asking if they can revert your use of gold pass
