Subscription

I do have this subscription that i forgot to cancel before the free trial expires. So july 15 I received email from my bank that my card declined since i do have insufficient balance and that time i remember the subscription renewal day so i canceled the subscription right away, but that night i deposited my check and waiting for them to deduct the amount i owed since i canceled it late. i’m just worried i might have debt to them. which is i’m willing to pay if i have too.
