Absa double debit order

Absa debit order management on internal accounts is shockingly poor. My absa vehicle finance december debit order was moved to the 14th without consent, but I got paid on the 19th. Then there was a 2nd debit order run for the same amount on the 26th december. This can't be reversed in the app as it exceeds the app limit. There are no suitable options or contacts available on their customer service line. I now have to wait a day to phone again or go into a branch. What a huge inconvenience and negative impact while being on holiday. This impacts my other debit orders and available funds. There should be penanlties for this irresponsible business behaviour.
