I had previously received help in stopping auto renew because I had downgraded. It had stopped but now it's started again. I also have another which keeps trying to auto renew. I need both of these stopped.

I had previously received help at stopping auto renew of a payment for iCloud storage. I reduced that back down to the free storage amount. It had stopped trying to renew but is now back again. I would like that stopped please. I also have another account which was closed and is no longer being used and it keeps trying to renew so I no longer pay for that service and it's Google. I need both these auto renew's stopped.
