MiWay ********** Debit Order

I am disappointed that MiWay has decided to deduct money from my account on a day I did not agree on with them making this a ********** transaction. I have called them and they have not taken any responsibility for #1 deducting money on a day I did not authorise, #2 Deducting way before my paydate thus leaving me on a negative bank balance. They have not acknowledged the error and have not taken responsibility for the negative charges that the bank will impose because of their recklessness.
