Absa double debit order deduction!

So absa just debited my account twice with my monthly loan installment. I called the telephone contact centre and was advised they cannot reverse debits for their own products. How ridiculous! I now need to wait until Monday to call the personal loans department to find out why this has happened (when clearly someone, somewhere, messed up because I was not informed of any intentions on their part to do a double deduction - but now I have to do the running around to fix their problem) and then have to have another likely fight with likely another *********** agent trying to get my own money back which they took without my permission. Sigh. It’s almost a new year, maybe it’s high time I move to a new bank.
