Disappointed

There was ***** done online using my premium credit card about 2-3 weeks already . I immediately blocked the card when finding out and called the ***** department. A case number was given, till now one contacted me. Also I noticed after checking my internet banking that absa only sent me one message for one amount to authorize and not both or all amounts . Firstly nothing was authorized by me, and secondly it’s quite a substantial amount for me to wait for an investigation to be done because all my debit orders hit back through Absa negligence. It’s evidently ***** because my card was used to book overseas tickets both on one persons name as travelers. The total amount of ***** committed was approximately 30k . I have all proof of money taken out and also proof that only one authorization message was sent to me and how was it approved also?
