Hi
I have a tax-free child govt account, whereby the govt tops up by 20% each month.
Each month I transfer £672 as my nursery bill is £840pm.
Can anyone explain why some months the top up is £168 and so the £840 is covered, yet this month it's been £164 which means the payment didn't process to the nursery as there was only £836 in the account 
Thanks !!!
