Netflix abo change how does the deduction go?

If I now have a Netflix abo for 7.99 and it changes so that I have to pay 10.99 is automatically deducted then in the same month 3 euro more? What if I make tomorrow for 7.99 again? Was I then the 3 euro again or how it works

That depends on when your money is deducted with me it was so I had an account for 7.99 and the next day the money should be deducted then I have the day before the 7.99 should be deducted on an account for 13.99 and it was deducted the next day 13.99 I think you would not get your money back it would then in the next month, then simply back to 7.99
