UNAUTHORIZED DEBIT ORDER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

DO NOT MAKE ME LOSE IT!!!!!!!!!!!!!!!!!!! I have just received an SMS now telling me that my debit order will be deducted on 18/12/2018 at 00:00:00. Is this some sort of a prank or what????????????????????????? My debit order date is the 25th of every month and i never authorized an early payment as i will not be paid yet. Someone need to call me urgently as i also have other inquiries to make. Should this debit order reverse and i incur penalties, you will pay for them!!!!!!!!!!!!!!
