ABSA not giving my money back

Now exactly a month ago i have bought a flight ticked using my Debit card ,the money didnt clear from my account and i phones the clearance department to clear the money into the airway provider and they said it will take 48h to clear ,unfortunately my booking for the flight will be the following day ,so i went to the bank and asked them to cancel the transaction and return the money into my account as i then paid with a credit card to get the booking confirmation and tickets,i was sitting at the bank in line for 2,5 hours only to be told they will clear it in the next 48h then the airway can refund me the money ,as of today i have send numerous emails to Absa to release or even refund my transaction for R23000 as it is still showing pending on my account and nothing is been done? My money is just floating there somewhere and ABSA isnt helping at all ,i have all my accounts with them ,my personal and a multi-million rand a year business account with them ,but im now considering moving all my accounts as the service is non existent Absa i want my money
