Running debit order before agreed date

Capitec decided that they should run my debit order from the 19th even though I only get paid on the 27th and my pay slip states the last day of the month. Obviously the debit order didn't go through. Now I'm being charged additional bank charges for a failed debit order. Worst thing is that I've had this personal loan for more than two years and have never missed a payment. Will be reporting Capitec as I never agreed for any debit order to run on the 19th.
