Credit card transaction reversal

<p>I booked a flight online and I received an email confirming the order unsuccessful. I contacted the airline and they told me that the bank did not authorise the transaction. The money shows that it went off the account. I called ABSA and they say they cannot reverse it! How? I need to book flights for this Friday and cannot book again. According to ABSA this may take 30 to 50 days to resolve. This is unacceptable. I need the money reversed ASAP.</p>
