Unsuccessful transaction money not returned.

I withdraw money from a ABSA ATM and the transaction was unsuccessful but the money has not been returned to my account. Called your call center and I was told it will take up to 35 days to resolve the issue. More than a month! Make it make sense. Ya'll not even saying 48 hours the most while other banks returns your money in a split second before you even step away from the ATM. I have emailed "evidence", the slip that stated my transaction was unsuccessful to your *** and the Case ID Number that was sent to me via SMS.
