RCS bad customer service /support

On the 20th of November someone created a self service profile online using my card details and managed to make a cash advance for R8000. For some reason I got an otp sms from RCS and I called to find out what was happening, and that's when I was told that someone did the cash advance. I then asked the lady on the phone to block my card and reverse the transaction and she confirmed to me that it was reversed, to be sure I went into the store to verify and I was told yes it's blocked and the cash advance has been reversed. I recently got my statement and the cash advance has been deducted from my credit account and I have tried sending emails to rcs with no help with regards to the issue, seems like they are working with these ********* because I asked if they can show which bank account the cash advance went to they said they cannot see that? I am to date waiting for assistance but none is coming my way.
