BUDGET - USE THE CORRECT CALENDAR

Budget insurance has decided to debit their money before the agreed debit date. We agreed that they need to debit their money on the 25th of every month, unless the 25th falls over the weekend then they debit on the Friday of that weekend. This month (July), the 25th is tomorrow (Tuesday), but Budget has already debited their money today, which messes up my own budget. They must stick to the agreement.
