Uncleared transaction for more that 3 weeks on my ABSA account.

I filled my car at Sasol with my debit card. It was declined although there was enough money in my account. The reason was "Finalisation Error". As this transaction was "Uncleared" on my account I paid with my Credit Card. The transaction was approved. This was on the 12th of April 2025. As of today the 2nd of May 2025 the transaction is still uncleared on my account. I called absa and they said I must send an e-mail. I asked if I could go to a branch and the lady said "Yes". After spending an hour in a very busy branch, the Customer service phoned and she was told that I have to send an e-mail. The "Uncleared " amount does not show on ABSA's system. I did not get a refference number fot the call. I am very disappointed in this service after being a client since 1988.
