how to deactivate game pass on riot account that is banned?

Hi. My name is Brilliant, an independent advisor, happy to assist you today.

If you are unable to login to deactivate the subscription, there pretty much isn't anything you can do about it. You will have to access your old account to cancel / deactivate the subscription.

Hello Milancho N, My name is David. I am an independent advisor, happy to help you today.

I'm sorry to hear that your Riot account has been banned. To disable game pass on the banned account, follow these steps:

Visit the services and subscriptions page of your Microsoft account.
Find your Xbox Game Pass subscription and select “Manage.”
Select “Turn off recurring billing” to stop recurring charging.

Best regards.

it is already off i did that as soon as i bought the game pass. I think you don't realize what the issue is so basically i redeemed my xbox game pass perk on my old League of legends account which is currently banned bc someone used it and got my account banned i don't know the specific reason. I want to get the perk on my main account (the new account i made around 2 weeks ago) and when i log into the launcher and start the game on the old account I get an error saying i am banned so i can't even use the champions i got from the perk.

I believe you need Xbox Gamepass and an Xbox account.

See below.

Ok If you’re an Xbox Game Pass member and your Riot Account isn’t receiving Game Pass member benefits more than 24 hours after linking your Xbox profile, you will need to contact Riot Player Support.
