Netflix voucher money?

How is it if I get a voucher for 15 euro but want the package for 8 euro? Will the remaining 7 euro be credited for the next month?

Yes, the remaining amount is retained. Of course, the remaining 7 euro are not enough for another month with an 8 euro subscription. You always have to pay full months, you can't use them up proportionately.

Yes, they will, it works like a SIM card with credit, recharge, use… Repeat.

If you don't buy new credit, nothing will be deducted. So the balance remains until you top up money again.

Thank you, too!
