Debit order deduction before pay date

This will be the first time I have an issue with MFC. They send me an SMS stating they will deduct my premium before salary date due the which is 27th April. MFC wants to deduct 26th April. The SMS stated that if you need to call should there be a problem. Which I did and I got told that on receiving the SMS today the date is already loaded as 26th and they cannot change it. Banks and all other institute's normally take it later after the holidays. It's a first where they take it even before your pay date. Your system needs to upgraded to accommodate holidays like all other institute's. This is an inconvenience to the customer.
