Trial expired and not paid?

So if you start a trial subscription in an account now and it expires and you can't pay the money, e.g. Not enough money / no money on the account because there are reminders and is it the same for every company? For example, Amazon Prime, Netflix ect.

Sample is called sample. What comes after that you have to pay. If not, as you already say, reminders flutter in. So read it through before you conclude an abo as it looks with the timely termination.

Oh dear, that would be too late
