Waiting on response on ********** transaction

On the 6th of May I called the Credit Card Division to report a transaction I did not make, turns out the transaction happened on the 4th of May as per the call centre agent and my credit card was cleared of available funds. I was given a reference code SFHUQPEHHN told that I should expect a response within 30 days. When I called the centre back after June 6th I was told the inquiry into the transaction only started on May 22nd. No answer was given as to why it was started so late but I should expect a call from the relevant department and that it should be finalised by June 22nd. Today is June 22nd and I have still not received a call from said department nor any update. This is now the third time ABSA has *****ed me on my account. The previous two were blocking my accounts for outstanding FICA documents within a month of each other. No attempt was ever made to contact me regarding the documents, my account was just blocked and I found this out while trying to pay for goods. Can I expect a response or should I just accept the loss and move over to another bank?!
