Incorrect debit date

I have had a debit order with truworths for many years now and it has never returned.<br> This month, the debit was deducted on 22.05.2015 & i only get paid on the 27th of every month.<br> I did not request an earlier date, neither did they sms or call to ask if they can deduct earlier. had that been the case I wouldve informed them that it is not possible.<br> I have requested the debit order because it is more convenient but now this happens. Also, the bank charges associated with this transaction as well as the record on my bank account, who must be responsible for this??<br> I have been holding for 20 mins on the phone for Truworths but no one answers the phone. I cannot sit on hold all day. Please call me back before I get demanding sms's to pay.
