DEBIT ORDER NOT TAKEN

I have an agreement with mi way to debit my account on the 20th of every month which they always do. they decided to stop debiting my account without my request. i called them on the 13th of january 2015 to confirm if the debit order will go through for january they said yes. but it didnt go through still now i call them why it didnt go off they dont have an answer. <br> <br> they now say i dont have a cover for february because they didnt debit me. If this is how you treat your clients is this is not right because of your mistake. it breaks my heart because i always have to call to ask why you didnt debit my account. please look into this matter because we have an agreement to debit my account on the 20th.
