Uncleared transaction of about 2 weeks

I filled my car at an Engen garage on Friday, 18 April this year with my debit card. It was declined the first time and when we tried again the second time the payment was successful. When I went onto my app I noticed that the amount was deducted twice from my account. This was on the 18th of April 2025. I went too my nearest ABSA branch and the consultant confirmed that the one payment reflects as 'authorization' on the system which has not been cleared. She requested me to send an email to ***. I did send the email, I only got a reference nr and nothing was done about my case. As of today the 5th of May 2025, the amount has still not been reversed on my side. I am very disappointed with ABSA. I thought they were an efficient bank.
