Netflix payment error?

I have a problem Netflix could not debit from me because no money is in the account now the question is I have to pay now except the 7.99 euro still something z.b. Punishment or something

If you noticed it immediately, no. Otherwise reminder fees may be due.

They will inform you if they want money from you. Do not transfer money on your own

If it is debited from the bank, maybe 2-5 euro, depending on the bank, as repayment costs. Or you have a dispo on the bank. Then interest will come.
