They should have given you a letter or something to formally advise the fees are going up and to what. I used my letter to work it out manually
Without knowing the prices no one is going to be able to help. They should have sent a letter or an email stating the new prices. Ours have gone up £4 a full day £1 a day and 50p for early start. You can always cancel the payment you have set up and then when you get the invoice add the right money
I think every single nursery work out their bills, finding and fees differently. I’d just ask them when you’re there in person or wait for the bill. You can cancel the payment for now and then re set it up again once you know what it will be x
