Absa ***** useless and absa taking more money

I have been an absa client since 3 years old and will never use the ap again and considering changing banks for better security. Sunday 2 June ***** was committed on my credit card via the ap. A false log in not by me was sent via sms. R10141 Was taken from my credit card. I received an sms to ask if this was me by the ***** line I immediately phoned to say no stop the transaction. They cancelled the card and said I wouldn't be charged. I now have been charged this needs to be reversed absa as now you taking my money too my card wasn't lost or ****** it was hacked online. I also blocked all my app and Internet log ins. On my side the money showed uncleared but on the back end it was accepted by the ******. The money ****** was for an airline ticket and people need to give their name so this should be traced easily also you can cancel the ticket to get the money back, I didn't want to hamper the investigation but since I have had no feedback I think I need to try get hold of the airline myself and see if the ticket hasnt already been used if I can try cancel it myself on budget air dk. Please give me an updated ASAP so I can know if I must try investigating myself to get my money back and reverse the money for my new credit card as the ***** line said they wouldn't charge me. I have phoned the ***** line numerous times and no one has answers on what I should do. I also do not want to be charged interest on this money they took on my card that is now seen as me owing money on my card how do I fix this do I need to pay that money back in ASAP so I don't pay interest??
