Credit Card ***** Investigation going on for 6 months now - still no feedbac****!!

I reported ********** transactions that went through on my ABSA Credit card early Feb 2019. I am told investigations are in progress, but have to follow up constantly for feedback. The only activity that seems to be happening on these investigations is that I'm handed to a new consultant every time and then I wait another 4 weeks, only to be told, the investigation continues. I would like the R5800 PLAYSTATION transactions removed from my account. Please can I request that a manager or a decision maker resolves my issue. I have been patient long enough, in fact it's going on for 6 months now!!!
