Debit Order

I have a policy with Holland and my date of deduction is 27th each month i understand this month the 27th was on Sunday so i expected my debit order to go off on Monday, now Hollands deducts on Tuesday the 29th and there is no money in my bank so now i have bank charges that i need to pay please cancel this policy i will go somewhere else. i will not afford double deductions on my account plus the bank charges of the stop order...Your service is inconveniencing me.
