Terrible service paying back money taken without authorization

Transacted with an instant EFT service paying money to Luno which was facilitated by ABSA. The transaction was reversed so I made arrangements with Luno to pay the money to them using a normal EFT. However one month later that R1030 was deducted from my capitec account without any authorization given by me. I have been in contact with Luno and they have said that Absa is investigating the problem and will pay back the money but have not provided a timeframe for when this will happen. To me this is **************** and pathetic behavior from Absa not to pay back the money and now it's been more than a month since it was deducted from my account.
