Consequences of downgrading account immediately?

Hi, i just created a professional seller account but changed my mind about selling at the moment, but i still have future plans of selling. i would like to downgrade to an individual selling plan for the mean time. will i still need to pay or will it close my account if my account remain stagnant for the next months? i have no listings, no anything. i just literrally made my account. yet i don’t want to pay 39 usd for the next months.
