Credit card withdrawal fees

On the 4th of June I called client care to report that there has been a charge of R399 on my credit card for Withdrawals/Transfers whereas I havent withdrawn nor transfered money during the period... I was promised that my case will be escalated and resolved within 72 hours at most but up to this day (38/07/2020) no feedback has been given.

When I call to follow up I do not get any info besides that my case is still with their investigators. On 26/07/2020 another R395 was charged. I do not even know where to start enquiring about it since even the first one hasnt been solved.

My reference number is ***6 and ***0
