accidentally started free trial

sooo, i hate having to come here about it, but im nervous because i cant afford to be charged. the free trial does not show up in my subscriptions, however i went through the contact and it said that the subscriptions auto-renewal was already turned off. is this true? i need to be sure, because again, i cannot afford to make a payment right now.

You don’t seem to have any subscriptions under the email address used on this forum.
