How to Change my OneStar Plan

New Contributor

Hi I recently purchased a new Buick 2022 last month and now that my trial period is up in 2 days for OnStar I would like to change my plan from premium to a slightly lesser plan before I am charged for the first month.

I can't seem to find any information on how to do that or how to turn off automatic payments so I don't get charged $50 that I don't want to spend!
